Field Trip with a Twist

We’ve  just returned from an extra special field trip – not only could all our team make it out to PKWS to check camera-traps and conduct workshops with communities, but we were joined by 2 volunteers:  seasoned tracker extraordinaire Abel Ferrer from Spain and Biology graduate Alba Maya all the way from Mexico!

They joined  our Community and Research teams to deliver training to PKWS  rangers on tracking using materials developed by Vanessa, supplemented by existing materials from Wildlife Alliance:

Training PKWS rangers

This was just a small part of the 2 days’ training our team conducted, which opened with a plenary for rangers to share their views, experience  and perceptions of wildlife within their patrol area. This allowed for insight into rangers’ knowledge, passion and motivation for the job.

Day 1: Theory

We also screened photo and video captures from our camera-traps- to enable greater understanding of our scope of work- and invited comments from rangers.

The team facilitated interactive mapping of the area, with rangers contributing local names of streams, plus indicating where and how often they patrol, what they see at each location etc – these insights will inform future camera-trap placements.

Also on the agenda was discussion of a wildlife data collection system, including implementation of a user-friendly system to train on SMART (Spatial Monitoring and Reporting Tool) in future.

By the end of the day, we had jointly identified key sites to visit on Day 2.

Day 2: Practice

A group of 12, we set out on boats to check out the sites and replace a camera-trap at a since discovered good site for Fishing Cat.

Along the way, we talked wildlife in the area and trained rangers in setting up camera-traps.

Sothearen explains camera trap set-up

Our hope is that this immersive engagement can form the basis of future collaboration and knowledge-sharing with PKWS rangers.

Most exciting of all, together we searched for a spot to deploy a new camera-trap.

The sign of a good day: new camera-trap set and ready to go!

This is just the first step – on upcoming field trips we aim to deepen this knowledge base, build capacity and contribute resources to make the work of rangers in the area more impactful and gather more detailed data about wildlife in the area- watch this space!

We would like to thank our donor Panthera for their continued support in this endeavour.

Fishing Cat still prowl PKWS

In February 2017, supported by Panthera, the Mohamed bin Zayed Species Conservation Fund and Denver Zoo, we placed 26 camera-traps in key mangrove habitat within PKWS.

Now we want to share the exciting results of our survey so far:  captures confirm an extant population in PKWS!

“This is a first glimpse of the fishing cat population in PKWS,” says our Principal Investigator Vanessa Herranz Muñoz, “but our preliminary findings are very promising.”

Fishing Cats caught on camera include an individual at a new site (above) negotiating aerial mangrove roots:

This camera-trap video of a Fishing Cat (Prionailurus viverrinus) was captured at a new site in the mangroves of Peam Krasop Wildlife Sanctuary, Koh Kong, south-west Cambodia. The individual cannot be identified from current captures but surveying for Fishing Cat in the area is ongoing.

and the female identified in 2015 at her old haunt (below), a raised platform next to a stream which provides much-needed dry land for marking.

Cameras record her doing just this, part of a “fascinating display of the intimate life of fishing cats in the wild.” See video below:

“The recapture of the female fishing cat after two years is good news,” says Dr Jan F Kamler, Southeast Asia Leopard Program Coordinator for Panthera, “as it indicates snaring could not have been high in that area.”

Our threat assessment, conducted with local communities, bears this out. Back in 2015, killings of fishing cats in PKWS in retaliation for damaging fishers’ nets was identified as a major conservation challenge, but the cats may no longer be viewed as a threat to livelihoods notes Community Officer Sothearen Thi: “People have no will to hunt or kill fishing cats because there is no perceived conflict.” What’s more, villagers welcomed measures to mitigate future human-fishing cat conflict. Vanessa sees this as a very positive sign and is hopeful that “together we can ensure that fishing cats persist in the Cambodian mangroves.” For other species photo captures see here.

Protecting what’s precious

Globally, the feline faces a multitude of threats, from habitat destruction to active persecution, which have led to a steep decline in its numbers- suspected to be 30% or more over the last 15 years- culminating in the declaration in the latest IUCN Redlist assessment that the fishing cat “faces a high risk of extinction throughout its range.” Nowhere is that risk more acute than in Southeast Asia where it is believed to be amongst the most vulnerable of the small and medium sized cats.

Research on the species was initiated only in 2009 but already it is believed extinct in Vietnam with no confirmed records in Laos PDR and scarce information about the species in Java, Myanmar, Thailand and Cambodia.

Fishing Cat range adapted from IUCN Redlist 2016 assessment

Our results follow closely on the heels of sad news from Java: a recent extensive survey targeting Fishing Cat yielded no records. “Nevertheless, fishing cats still exist across a wide range,” Dr Frédéric Launay, Director-General of the Mohamed bin Zayed Species Conservation Fund (MbZ) told Cat Watch, “and our focus should be on assessing population health and reducing threats elsewhere.”

In light of this, just such an assessment yielding evidence of an extant population can only be a good thing. On the other hand, our findings indicate that individuals in PKWS may be restricted to the largest islet of the protected area. Could this be another remnant population such as those in Central and South Thailand, highly localized and restricted to a small area? Only further surveying will tell.

So far as suitable (and safe) habitat in Cambodia goes, the population inhabits a protected area whose zoning- approved in 2011- is seen as an important pilot for the rest of the country.

What’s more, 60% of PKWS falls within the Koh Kapik and Associated Islets Ramsar Site– where the Critically Endangered Spoon-billed Sandpiper was recently recorded– which should afford the sanctuary additional protection.

PKWS population in the clear?

As leader of the 2015 survey and Project Research Consultant Ret Thaung notes, Fishing Cat numbers have declined dramatically as Asian wetland habitats rapidly disappear or are modified by human activity. Since the 1970s, industrial shrimp farms have accounted for a large part of this habitat loss in Southeast Asia. In PKWS, however, shrimp farming fizzled out in the early 2000s- today it is virtually absent, and much of the mangrove destroyed has been restored.

Furthermore, communities report that hunting is infrequent in the area, thus Fishing Cat in PKWS may be relatively safe from the snaring crisis which is sweeping Asian forests, according to a group of scientists (including Wildlife Alliance director of science and global development Dr Thomas Gray) writing recently in Science. Dr Jan F Kamler notes that snares are “a major issue for most wildlife in Cambodia and other areas of Southeast Asia,” which, as the authors acknowledge, kill and maim indiscriminately “any individual that encounters them.”

This being the case, Fishing Cat are also vulnerable to snaring, infrequent as it might be in the area – one man informed us that a Fishing Cat was killed in a snare set for Water Monitor in late 2016 and supplied a photograph:

As in 2015, communities are highly dependent upon fisheries in PKWS but “think they don’t use illegal methods for fishing activities,” Sothearan noted following interviews with villagers.

In order to further reduce threats to Fishing Cats, Kla Trey is collaborating with the leading organization for direct protection of threatened habitat and species in the country, Wildlife Alliance. Their mobile environmental education unit conducted awareness raising workshops alongside Kla Trey staff.

After collaborating in PKWS, thanks to Wildlife Alliance, awareness to protect fishing cats will reach communities throughout Cambodia!

We will work together closely to promote the “importance of coastal zone conservation in the Cardamom Landscape – something for which the Fishing Cat is an important flagship,” Wildlife Alliance director of science and global development Dr Thomas Gray told local press in January. Herranz Muñoz has since joined him in neighboring Botum Sakor National Park to deliver training to wildlife rangers on camera-trapping targeting Fishing Cats as part of continuing research on their distribution within the Cardamom Landscape.

Additionally, we will continue to work with local authorities, the IUCN and others to build capacity and enhance local knowledge of protected area management, facilitating alternative sustainable livelihood options for PKWS communities where possible.

Fishing Cat status in Southeast Asia

While it’s true that our results, including those from our threat assessment, allay fears about the population in PKWS, globally Fishing Cat status remains grave. It is important to note that the change in its IUCN Redlist status from Endangered in 2010 to Vulnerable in 2016 is a “non-genuine change reflecting the very recent increase in information quality; it does not indicate an improved conservation status for the species since the last assessment,” in the view of the assessors, including our Principal Investigator Vanessa.

We remain hopeful however that forthcoming surveys in Myanmar, mounted by world recognized small cat expert and fellow Fishing Cat Working Group member Dr Jim Sanderson in concert with local conservationists, reveal populations there.

The Future for Fishing Cats in PKWS

Suffice to say, we have considerable work ahead of us to further assess and survey suitable habitat within PKWS, which offers one of the most formidable landscapes in Cambodia in addition to some of the largest and densest mangrove forests in Southeast Asia.

Much of this forest is intact however, and the fact that mangroves are notoriously inaccessible, thus consistently under-surveyed, cannot be overstated – recent research suggests that they provide an important refuge for threatened species, especially primates and felids.

We cannot help but agree with fellow Fishing Cat Working Group member Sri Lankan researcher Anya Ratnayaka that the Fishing Cat is the “most charismatic focal species to be found [in the world’s] wetlands.” Our Project to preserve and protect them in the mangroves of Cambodia is just beginning.

Fishing Cat habitat part of new protected area network

Coastal mangroves are now contiguous with a protected area network of nearly 2.4 million ha

In May 2016, the Royal Government of Cambodia (RGC) declared five new protected areas (PAs) covering over one million ha of forest and grassland. This brings the total coverage of the national protected area system to 34% of the Cambodian land surface (Central Intelligence Agency, 2016; Open Development Cambodia, 2016b).

Biodiversity status

Cambodia forms part of the Indo-Burma biodiversity hotspot which, with its high levels of fauna and flora endemism, and limited remaining natural habitat, ranks among the top 10 for irreplaceability and top five for threat, according to the IUCN. Alarmingly, 37% of the key biodiversity areas within the region are not under any formal protection.

Fishing Cat habitat within protected area network

Amongst the new PAs declared is Chuo Phnom Kravanh Khang Tbong National Park, which links the Central Cardamom Mountains National Park with Tatai Wildlife Sanctuary, and connects the ridges of the Cardamom Mountains to the coastal mangroves at Peam Krosaop Wildlife Sanctuary (PKWS), a possible Fishing Cat stronghold in SE Asia, and Botum-Sakor National Park.

Figure 1: Protected areas designated in Cambodia in 2016 (light green): 1) Chuo Phnom Kravanh Khang Tbong National Park; previously established protected areas (dark green): A) Phnom Samkos Wildlife Sanctuary, B) Central Cardamom Mountains National Park, C) Phnom Aural Wildlife Sanctuary, D) Peam Krasop Wildlife Sanctuary, E) Tatai Wildlife Sanctuary, F) Botum-Sakor National Park, G) Samlaut Multiple Use area (Map adapted from by Souter at el 2016).

 

The contiguous protected area network through and adjoining the Cardamom Mountains now covers nearly 2.4 million ha (Open Development Cambodia, 2016b,c), stretching as far north as Samlaut Multiple Use area in Cambodia; Namtok Khlong Kaew National Park and Khlong Kruewai Chalearm Phrakiat Wildlife Sanctuary in Thailand.

More protection for the Fishing Cat

The declaration confers greater protection on the Fishing Cat as a species within the Cardamoms landscape, where there have been numerous records of the species: seized individuals from a village close to Botum Sakor National Park in 2008 (Royan 2009), two Fishing Cat kittens from Prey Nop district and from Koh Kong province in 2014, both courtesy of the Wildlife Alliance Wildlife Rapid Rescue Team (WRRT) (Gauntlett, pers comm), and a pelt discovered in Phnom Samkoh Wildlife Sanctuary (north Cardamom Mountains) by FFI staff in 2015. (Read more…)

Greater genetic diversity of Fishing Cat populations

Connectivity yields the possibility of greater genetic exchange between populations, enabling even transnational migration of Fishing Cats, thus strengthening the case for continued surveying of Fishing Cats across the landscape in order to characterise the metapopulation.

Other threatened species in the Cardamoms landscape

The expansion of the Cardamom Mountains protected landscape should reduce risk to 54 other globally threatened species (Killeen, 2012), especially Endangered Asian elephants (Elephas maximus) threatened with habitat fragmentation.

It may also benefit future tiger (Panthera tigris) populations; the National Park has been identified as a priority site for tiger restoration in Cambodia (DWB/GTI, 2016)- native Indochinese tigers were declared functionally extinct in the country in 2016 (Read more).

Future additional protections- UNESCO Man and Biosphere Reserve

The new declaration as Souter et al. (2016) point out, “strengthens justifications for designation of the area as a UNESCO Man and Biosphere Reserve [MAB].” Such reserves aim to integrate people and nature for sustainable development, involving multiple stakeholder agreement in designated zoning with various levels of protection, from maximum protection within core zones to transition zones where regulated activities may take place. Importantly, UNESCO MAB is a globally recognised figure, likely yielding increased investment in biodiversity research and conservation efforts, which is crucial within a protected area system which is severely underfunded (Souter et al. 2016).

In conclusion, we join Souter et al. (2016) and the conservation NGOs they represent in disseminating news of the RGC declaration, and hope that this and future decisions help to direct resources and technical support towards areas rich in biodiversity within a Hotspot that is one of the most biologically rich- and highly threatened- places in the world.
