The global threats facing keystone species is significantly impacting levels of biodiversity, due to the disproportionate effects keystones have on entire communities. They influence trophic interactions and provide ecosystem services of vital importance to the economic, social and cultural well-being of humans. It is therefore in our interest to establish the threats, the individuals most at risk, the potential cascading effects on ecosystems and how we are to manage them successfully in terms of reintroduction or mitigation. In this essay I review the major threats to a variety of different keystone species (at all trophic levels), examine how this influences levels of biodiversity and what effects they have on entire ecosystems. I also evaluate the current and potential management strategies that facilitate networks and allow them to be more resilient to future environmental change. Our knowledge of the concepts that underpin the fundamental basis of ecology can help us confront this as one of the greatest challenges in ecology.

Concept of Keystones

In different ecosystems, each specie plays a role within a community and can influence levels of biodiversity. However, the relative impact of each species can vary in terms of importance [27]. Such species that have disproportionate effects on ecosystems are known as keystone species [39]. According to network theory, keystones are intimately linked via ecological networks of highly connected and complex webs (Box 1, [9]). These include species at different trophic levels. Apex predators exert top-down effect on these levels, known as trophic cascades; whereby these strongly connected species indirectly influence community structure and ecosystem function [37]. The robustness of food webs to species removals varies, depending on the species and ecosystem type, where certain removals have greater impacts on ecosystem functioning and structure. Many apex predators are classed as keystone species because of the secondary extinction impacts of their removal on other species [7]. Predators directly impact upon herbivore numbers as well as indirectly through risk effects [34]. This then influences the relative abundance of producers- hence a ‘cascading effect.’

trophic cascasde

Equally, predators sustain levels of biodiversity via the suppression of other competitors (mesopredators) through competitive exclusion, and allow other species to co-exist [20]. Predatory release occurs when the apex predator is removed, increasing populations of the less competitive mesopredator. This then leads to a decline in its prey. Predator-prey dynamics as well as competition between intra and interspecific species also influence the structure of the food webs [1, 27]. The length of food webs can also greatly influence the direction of the cascade according to the exploitation ecosystem hypothesis [11]. These natural processes can be perturbed by threats to apex predators- whereby the removal of such keystone species leads to the concept of trophic downgrading [10]. As well as this, there is an alternate stable; where ecosystems are disturbed to such an extent that the cascade shifts from its prior state to another- when a tipping point is reached [10].

Box 1- Network theory

The fragile nature of ecosystems has been explored by Sole and Montoya [36], on the basis that if the nodes that connect individuals are randomly removed in a network, it remains stable. However, when highly connected individual are removed, this results in cascading effects and interference throughout the rest of the network. These keystone individuals form the framework and structure of the network. In real ecological networks, strong evidence for the removal of predators are known to not only directly impact its prey, but also have indirect effects via top-down forcing. Ecosystems processes such as primary production, nitrogen cycling and the establishment of invasive species are also affected (Figure 3 [10]).

Keystones – threats to a complex web of interactions

Habitat destruction

There have been major declines in biodiversity within recent decades, in what has been described as the 6th mass extinction event [27]. The threats facing keystones and the ecosystem services they provide are predominantly anthropogenic [19], and habitat loss is arguably one of the greatest [15]. For example, the Yellow and Black-Casqued Hornbills are both in decline, which has been correlated with deforestation in Nigeria as well as forest sections along the Ivory Coast [28]. This is problematic in that the genera Ceratogyma are key seed dispersers of fruiting trees, and play an important role in maintaining the heterogeneity of forests and species diversity via gene flow [28]. Because of the large spatial distribution of their territories [45], up to 22% of lowland tropical rainforest species are dispersed by the 3 hornbill species within this genera [23]. Cultural ecosystem services include traditional ceremony wear as well as other benefits to the keystone tree species, Ficus, which in turn provides economic services to local tribes’ people. It is also an important food source for other species within the ecosystem [23].



Other threats to keystones include the urbanization of many habitats. Increased contact between humans and species drive them to exhibit behavioural plasticity and alter their behaviour [33]. A majority of studies indicate that increases in urban environments decreases species richness [35], due to disturbances in breeding patterns, anti-predator behaviour, fitness, selection of habitat and overall population size. This has cascading effects along trophic levels [2]. The black-tailed prairie dog, a keystone specie, contributes to the health of steppe habitats by mixing the soil. This increases plant productivity and landscape heterogeneity as well as providing coyotes with a food source [3]. Their overall numbers have decreased as a result of increased urbanization. However, in contrary to the risk-disturbance hypothesis, where increases in anti-predatory behaviours (such as vigilance) are seen, some populations exhibiting behavioural plasticity have reduced their vigilance due to habituation [12]. This has negatively impacted the vegetation due to increased foraging time, which has ‘rebounding’ effects back up the trophic cascade, on other herbivores and predators [33].

Climate change

Complex plant-pollinator webs are also disturbed by habitat destruction due to their sensitivity to perturbation [29]. This is the case with the keystone plant mutualist, Heliconia tortuosa,

Figure 1. The warming trend set to continue: (Left) Projected increases in temperature by 2081-2100 if mitigation and use of renewable resources is adopted. (Right) These are the predictions if the business as usual strategy continues (source: IPCC, Fifth assessment, 2014).


which supports a variety of hummingbird species, and is considered a central node in this web interaction [17]. Recent work has provided evidence for the fragmentation hypothesis, where forest composition is fundamental to the reproduction of H. tortuosa. Thus, the reduction in heterogeneous landscapes due to deforestation is thought to alter both plant distribution and pollinator behaviour, leading to declines in both populations [29]. Equally, other systems have also shown that deforestation alters pollinator behaviour. Phaethornis hummingbirds will take longer flight paths to avoid deforest patches and agricultural landscapes, decreasing pollinator efficiency. This affects the survival of plant species dependent on this mutually beneficial ecological interaction- and has led to regional declines in biodiversity [16].


Climate change also poses a major threat to the biodiversity of keystone pollinators (such as bats, bees and birds [19]). One third of the world’s crop production is met by the ecosystem services provided by insect pollinators [30], with agricultural pollinator services estimate to be worth £120 billion per acre, annually [40]. Phenological shifts are also increasingly being observed, with the impact evident in both pollinator and plant keystone species [4]. In Japan, seed production in Corydalis ambigua and Gagea lutea decreased due to the warmer temperatures causing them to bloom earlier, resulting in phenological mismatching with its key pollinator, Apis Mellifera. Consequently, this reduced pollination efficiency and success [31]. Climate change has also altered bee distributions and caused phenological shifts in their flight period. Predictions suggest that the spatial shifts in bee movements will be faster than that of its food resource, also causing phenological mismatching and decrease wildflower pollination [4]. Therefore, climate change poses not only a threat to the keystone plant-pollinators, but to other communities dependent on wildflower meadow species [31]. This highlights the fragility of these mutualistic interactions as key nodes in an ecosystem, due to their varying response to temperature change.

A major issue with climate change is predicting the influence it will have on biological communities in the future [13]. The polar bear (Ursus maritimus) is an apex predator in the Arctic ecosystem which is very sensitive to changes in sea ice cover, where it hunts, migrates and reproduces [25]. The rate of temperature increase in the Arctic and northern regions have doubled in recent years, reducing sea ice cover [24]. In particular, over the past 30 years, the Western Hudson Bay has seen earlier ice break up as well as reduced snow fall (Figure 2). The impact on ringed seals (a keystone specie) with longer ice-free summers has subsequently lead to changes in polar bear behaviour [25]. The continuity of this pattern threatens seal pup survival as they are forced to swim for longer periods of time in open water, exposing them to predation [13]. Ringed seals provide polar bears with net wet weight calorific gains of 2.2-5.3 kcal/g [43], and the decreased recruitment of ringed seals has driven polar bears to target nesting birds, as they are unable to gain sufficient energy [25]. This warming trend is set to continue with possible increases in temperature of 5.0-6.4˚C by 2081-2100 (Figure 1, [24]).

Hunting and over-exploitation

Hunting and over exploitation is also a prevalent threat to many keystones worldwide. The removal of a keystone predator is a major cause of secondary extinctions, demonstrating the strong influence of top-down effects on lower trophic levels [10]. This was seen with the expatriation of the Grey wolf in Yellowstone during 1935 (due to hunting), which increased populations of elk as a result of predatory release [39]. Increased levels of browsing on aspen, cotton and willow saplings in riparian river systems led to a more homogenous landscape and reduced diversity [34]. The wolf played a vital ecosystem role by maintaining diversity as well as healthy numbers of mesopredator populations. Classic studies of the consequences of predator removal are also illustrated with sea otters [10]. Enhydra lutris was nearly hunted to extinction by Russian fur traders at the beginning of the 20th century, resulting in the predatory release of sea urchins, which reduced Kelp forests by intensively over-browsing [42]. However, with the return of the otter during the 1970’s to certain areas, the recovery of the kelp forests was observed due to the effects of top-down control on urchins. The kelp populations in regions where otters were unable to recolonize did not recover [11], demonstrating how the impact of hunting can alter and result in the simplification of food webs.


The general pattern of global declines in apex predators is a cause for concern, due their strong connectedness in ecosystems and influence in altering the stability of food webs [19]. This is less well studied in marine ecosystems [20]. For example, sharks are apex predators in marine ecosystems [22], and are threatened by hunting. Demand for shark fin during the 90’s increased mortality rates by 80%. Many debate the function of sharks as keystone predators [8], however more recent studies suggest that although not all shark species can be described as keystones, some are key in structuring some ecosystems [44]. Indeed, strong arguments made by Estes et al., [10] concluded that the top-down effects exerted by apex predators are equally as influential as bottom-up effects. In Western Australia, Tiger sharks are considered a keystone apex predator; as mesopredator diversity (dolphins) and herbivores (dugongs) abundance are indirectly affected by the “seascape of risk,” as well as by direct predation [20]. 15 years of data collection in Shark Bay has supported the idea that the non-predatory effects of top apex consumers (predator keystones), play a pivotal role in influencing ecosystems [10]. Thus shark declines are affecting mesopredator numbers and behaviour, with unknown consequences on the rest of the aquatic communities [44].

Clearly, hunting apex predators can have detrimental, aggregating effects on lower trophic levels, both directly (via predation) or indirectly (through the landscape/seascape of fear concept). Equally, the idea that keystone’s play a role within and across communities [27], was seen with the decline of sea otters in the Aleutian archipelago populations due to increased predation by Orca [42]. The overexploitation of fish stocks in these waters in turn reduced populations of pinniped that fed on them [11]. This altered the orcas behaviour which began targeting otters as an alternative food source. Kelp forests once again declined as urchins were free of predation. This is known as the exploitation ecosystems hypothesis, where the food-chain length determines the level of influence and control top-down or bottom-up systems have in the primary productivity of ecosystems [10, 11].

Future: Management, mitigation and reintroduction


In terms of keystone species, the challenges of managing and mitigating their decline arise due to the complexity and interconnectedness between the many species they affect within ecological communities [5]. For example, managing the declines of seed dispersers is hard due to the large spatial ranges of their territories and difficulty in quantifying dispersal rates [23]. The extent to which urban-adapted keystones will affect the rest of the community depends on their ability exhibit behavioural plasticity and adapt, which varies between species and landscape scale [35].

The threat of climate change is also difficult to predict, thus is hard to prevent plant-pollinator loss in the future as phenological shifts continue at different rates [4]. Similarly, the uncertainty surrounding model projections of sea ice loss threatens the future survival of many Arctic species [25]. In aquatic systems, the lack of protection out of marine conservation areas and the extensive movements of keystone predators such as sharks, creates problems in managing and mitigating their decline [21, 22].

Equally, the overall concept of what constitutes a keystone species provides difficulties in management [7]. The definition can be broadly used to describe a spectrum of keystone types, which is confusing and problematic for conservation policy [7]. With an increasing number of species being given ‘keystone status,’ the lack of consistency in defining them more scientifically is rapidly becoming a challenge in itself [27].


Identification of which trophic direction is most influential in affecting levels of biodiversity within communities is controversial [10]. Often, it is dependent upon the ecosystem as well as the keystone specie. Some argue that primary production controls ecosystems bottom-up [18]. Others believe predatory top-down control is more influential, and is currently gaining more support due to the mounting evidence that global predator declines have significant impacts on communities and ecosystem processes (Figure 3, [10]). However, even if top-down systems were recognisably more important in structuring ecosystems, it is hard to determine the most prevalent impact predators have in influencing interactions within food webs- directly (through predation/lethal) or indirectly (risk effects/non-lethal [34]).

Figure 3: Indirect impacts of apex predators on different ecosystem function and processes (Source: Estes et al [10]).

Indeed, this is the case with sharks, where the importance of risk effects might be underestimated [26]. In terrestrial ecosystems, the ‘landscape of fear’ as well as direct predation by wolves is being taken into account in studies of natural systems, (eg: Białowieża Forest, Poland) in order to consider the nonlethal effects on herbivores [32]. Proposals by Manning et al., [34] suggest that controlled experiments in the Scottish highlands would provide much needed data and viable evidence for their reintroduction. However, public opinion is often divided in terms of reintroductions [37], and the funding and costs of trial experimentation are deemed wasteful [32].

The nature of predicting ecosystem response with the removal of a keystone is also very difficult when taken from a stable environment- where prior knowledge of the response in unknown [36]. Only a few studies have examples of networks that are partially mapped [5], and the substantial lack of data on a range of ecosystems makes management difficult [36]. Much earlier research does not indicate the strength of each trophic link, thus it is difficult to compare to the current consistent and empirically accurate data. Even when disrupted, other factors such as intraspecific competition can alter the response, and may take many years for the effects to propagate in the ecosystem [10]. Current strategies by the US Endangered Species Act fail to incorporate this [41].

Possible solutions?

It is vital that scientists are able to quantitatively asses the relative contribution of each proposed keystone [36]. Only then can policy makers implement management strategies that target and focus on protecting species that have the most important functional role- rather than the rarest specie [27]. We must also therefore demonstrate their functional importance before policy-makers act on the impetus of the analogical term of a keystone [7]. Of equal importance is understanding the connectivity of networks as well as attempting to mitigate the threats facing keystone apex predators. The geographic spatial scales at which natural or previously manipulated experimental removal experiments varies enormously, thus must also be considered in future reintroductions and management plans [39].


As already established, complex ecological concepts are hard to manage as many factors feed into the function, stability and persistence of food webs; including biotic and abiotic factors [10]. It is clear how important abiotic interactions greatly influence ecosystems and community structure and function, and must be considered if we are to manage and mitigate the effects of current and future climate change [19]. Therefore, as the fifth assessment by the IPCC suggests, anthropogenic climate change policy should focus on mitigation by following resilience pathways and realising adaption measures towards a more sustainable future [24]. If we are to reduce the number of extinctions, policy must also address the source of the problem; fossil fuel consumption, to mitigate the severe effects it could have on vulnerable keystones and their habitat [24].


Other concepts such as network theory have helped explain how the systematic targeting of particular keystone individuals is far more destructive than random removal [36]. Therefore fisheries must implement this into their harvesting methods and reduce their impact on sharks by implementing annual moratoriums to prevent over harvesting. This will require international cooperation to account for the spatial movements of these keystone predators [44].


The threats facing keystone species may arguably have the greatest impact upon ecosystem function and stability globally [10]. Keystone predators in particular play an important role as their loss is a cause of many secondary extinctions [21]. The complexity of these networks cannot be undermined, and scientists must now be able to predict and further assess why certain keystone species are more robust or more at risk from collapsing early on than others. This will determine which species will have the greatest impact upon the stability and function of communities [46]. Additionally, completion of fully described networks will need to be of a multidisciplinary manner, in order to expand upon the current knowledge of these systems. Mitigating the threats as well as assessing the success of keystone reintroductions in influence levels of biodiversity is also key [44]. The reduction of harmful human activities is also necessary in order to prevent future extinctions and declines in biodiversity [24]. Ultimately, the solutions to the challenges facing keystones and ecosystem function are not simple. However, further knowledge of how these systems work and the implementation of efficacious management strategies will lead more efficient restoration and protection.

Into the Mist: Day 1 of Deer shoot

6am wake up calls come very easily to me in the UK, mainly because the sun percolates through my curtains at that time, and partly down to the noisy customers that happen to be buying todays newspaper from the shop beneath us. But today I had even more of a reason- Deer filming!

Here is a short clip of the deer I got the week before, couldn’t resist this little fawn!

Here is the shot of the two male Red Deer having a par at each other…nothing too serious as it is late in the rutting season, so are winding down from their predominantly active season. Filmed with basic SLR (Canon 600D) and VERY basic £25 Tamron 70-300mm lens, so pardon the quality and jerkiness and lack of editing YET!

Harewood Park Start: Harewood Church Lane Distance: 5 miles Map: OS Explorer 297 Lower Wharfedale and Washburn Valley

We started near the church and headed down towards the stank and Carr wood, neat the road where the der tend to browse.

As part of the brilliant new YouTube Channel, Ecosapien, I work as a camerawoman to help get some of the story shots for the team to edit into one of the weekly episodes that David Bodenham broadcasts out. I am so grateful to be able to help out with something so exciting- the combination of stunning images with factual information targeted towards 13-25 year olds. Some more filming this Thursday so can’t wait! We parked up in a small neighbourhood (and yes we did check for a “Residents only” sign!) some way away from the deer park. Loaded up with a Manfretto Tripod, Canon 600D and Tamron 70-300mm I headed off with David to see if we could catch a glimpse of these beautiful British mammals. It was one of the most misty days I had come across being in England, and it was incredibly difficult to locate them at first. We headed down the side of the road to see if they had congregated by the roadside farmland, but with no luck. Back through the moss, thicket and ferns. It was truly magical walking through the forest that was so still. Quiet. Damp. Cool… The trees were playing tricks on my mind. Surely that tree was a deer? David assured me it wasn’t. I even had my contact lenses in at the time. I am certainly glad I had layered up correctly, the air was damp but very cold as well. Always put a thermal top underneath your clothes (sorry, love that Shakira song!) Then at the other side past the cattle grid we had more luck. The stalking began… This next stage of setting up your camera and trying out different lenses was really good fun for me. I have used my DSLR in lots of filming before but not at the adequate settings- aperture 5.6, 1080P 50f, ISO 200, white balance Auto. try it on your Canon model! We got a couple of establishing shots of the trees in the mist, just to highlight to the audience what the day was actually like! Then we saw the emblematic shape of antlers in the distance that soon enough melted away again in the depths of the mist. I could only hear the clashing and clanking of the antlers echoing through the mist as I crawled ever closer on the dew laded moss. It was thrilling. First Day Of Autumn In Richmond Park...LONDON, ENGLAND - SEPTEMB The next part of the shoot involved a lot more crawling. And yes, I got soaked but this is what you do to get the shot! it was so very worth it in the end after many failed attempts to get decent and clear shots. Never had getting soaked been so much fun! We stalked them all the way to the very same field that we had originally walked to, and for the very first time- I saw so males rutting! This is the best time of year to see deer rut (the mating season). The rutting month varies between species, but mostly it is during the autumn. You see the stags using their antlers in fearsome trials of strength during the rut (a Middle English word meaning ‘to roar’), and an enraged or injured stag can quite often be a dangerous animal. The episode is about the impact of the over browsing as Deer can have a huge impact on forestry operations. They cause extensive damage to young trees, either by stripping the leaves in the spring or by eating bark in winter or rubbing the velvet off their antlers in the summer. All of these actions can kill young trees. Many areas have to be deer-fenced to protect the trees until they are large enough to survive being browsed. Also, having no natural predators in the UK, deer numbers can become very high. For these reasons they are culled in many places. In another episode we will be talking about the reintroduction of wolves back to the UK, and I will be writing another feature soon! wolf-82e30 We had been able to find a small ditch as the side of the field that enabled us to get closer to them- we got some cracking shots of the males fighting it out in front of the females. With two stags, a third tried to join in! The males were pumped up, and also sniffing out the females. Brilliant day, I would highly recommend visiting Harewood to see them, and it is very much worth getting up early for.

You of course can actually if you go out of leeds on the A61 you will reach a large set of gates into the rear of Harewood. Then turn left and you can park there. If you go across the road, through the gates & turn left down a wooded path follow the path until it comes out through a wood gate back onto the main road turn left pass the main entrance and then take the next turn left on this road for 1/4 of a mile (no cars allowed) .You should see them on the right as the road drops down rather than get damp and mossy (but that’s the fun part!) You can also start from the village centre, parking at the village hall in Church Lane. The estate village of Harewood sits outside the entrance to Harewood House, one of Yorkshire’s premier stately homes. Other features include the Harewood Arms and the remains of a castle which we walked past on our trip down. h

Interview with Alex Jones

Alex Jones is wildlife cinematographer, producer, presenter, editor and extreme adventurer, who has created his own remarkable blue-chip documentaries as well as work on a whole host of films, TV shows and adverts. His unique skills using the EPIC Red have not gone unnoticed and he has recently won a prestigious Panda Award at the Wildscreen Film Festival, as well as his footage being used in a major new BBC series. I got the chance to chat to him about where his enthusiasm and love for wildlife all started.


Growing up in California, he has always been passionate about wildlife- picking up snakes at age of 9 in his backyard, and has been filming ever since he can remember. It surprises me when he mentions that he really aspired to become an entomologist, having seen him as a full-on explorer and cameraman, it is seemingly difficult to imagine Alex sat in his room pinning down another Panagaeus cruxmajor to his collection rather than being armed with an SD card and another 6 hours’ worth of footage.


“Their world is so different; a blade of grass can look like a tree from their perspective.”

And yet this makes sense; when you begin to look at his work. He has carried this love for what many would consider their worst nightmare over to what he loves filming- macro. His latest fascinating clips of a jumping spider, award nominated Curious snail and Sand-crabs were shot in his custom made set and studio which he built with his colleagues. They’re looking to get some sequences on side-winders as well as a variety of other hard-to film species, or those whose lives are largely left untold.

“To get the best quality footage, you’ve got to be able to get the lens ontop of them and have control the elements such as light, wind- except the behaviour of course!


He tells me about the most varied things he gets up to on a day to day basis. Deliberately seeking out danger, nothing seems to phase The Adventurer– going into caves, old mine shafts inhabited by a myriad of snakes and bats. One particular place he went to, which was even too extreme for Alex, was a cave powdered with volcanic ash.

“When you enter into the caves, its very tight, you have to crawl on your stomach. The ceiling felt like flour.” He tells me he was hoping not to get caught out by a cave collapse…

The most dangerous encounter? Without question- Crocodiles. He was wrestling one which had caught him from under the water, he says it was an incredibly intense moment, particularly since it was 8ft crocodile Vs an 5ft 6 Alex. He describes the moment where he was in the water when it brought him down, his friend and fellow cameraman came to the rescue, but even he admits it was a close shave.

He loves all aspects of wildlife filmmaking. Everything he does currently is reflected by what he has seen with the enigmatic blue-chip series, such as Blue planet. In terms of presenters, he used to present more hands-on like his childhood hero Steve Irwin. However, the more inclusive and poignant reminisces of Attenborough have inspired him to take on a more “BBC” approached style of presenting to camera, although I still believe the acting lessons will slip out now and then when he is overcome with excitement by a dangerous snake- more Steve Backshall then!

What else does he get up to? He tells me he’s working all the time, editing, researching animals to film, scenery shots with friends. However when he does have the time, he enjoys hiking, extreme surfing, rock climbing, spelunking in Thailand, Africa, California. His seemingly limitless supply of energy emanates through to his camerawork. The EPIC Red that he praises highly, is easy to programme to his specific needs, looks beautiful, sharp, and a professional “work horse,” which can cope with extreme conditions- rain, sand.

“It’s the elements that you don’t see behind the scenes, that’s tough on any camera.”(He’s of filming sand dunes).

He offers us his top tips if you’re filming out in extreme conditions.

“Be smart about what you’re doing, think on your feet, depending on the situation. Deserts in California and in Montana have two very extreme temperatures throughout the day, you have to love it too at the same time because it will get to you if you don’t.”

He admires the one and only award-winning Doug Allan and marvels at his endurance in his specialized field of polar cinematography. Talking of awards, he was very nervous about Wildscreen- his incredibly epic and thrilling shots of the beach master in California, won in the youth and against all odds category. He got the amazing opportunity to meet Doug Allan, Emma Blackwell, Fergus Beeley and many more! Here are some photos of the exciting awards night:

A Panda award!

What the most technically challenging shoot? The most challenging to film he tells me is his award nominated elephant seals of California.

“Only shot in 4 days, the first 2 days it was raining, but it was incredibly hard. The 4th day he got most of the shots. But was worried that I couldn’t get it all. I was all very stressful, equipment was failing too, weather bad, and I was alone with no help from crew. Intense! But staying with them all day you figure out behaviour, and with some smart thinking and being fast with your actions- it become the norm.”

He also tells me that it was emotionally hard sometimes to witness the helplessness of the seal pups being smothered by the testosterone pumped and over-amorous males which will crush anything and anyone in their way.


He’s recently joined the brilliantly exciting Animals bytes TV. His latest episode features a Rattlesnake which was made a year ago which they went off to find, check it out here:

“They’re the 2nd biggest, cause more deaths that any other snake- its very aggressive. My favourites are side-winders. I found it in a cave (200ft).” Just the day to day itinerary of a cameraman!


Having already secured one award under his belt, Nevada is next with his curious snail nomination. (See it here:).

Hopefully there will be lots to come from the Adventurer on our screens, we wish him the best of luck in his career! If you didn’t hear the interview for my radio show, catch up here:
