With luck and the continued support of all our hardworking scientists, volunteers and local communities the incredible species that inhabit these amazing forests will be able to call Wallacea home for a long time to come.Want to find out more about our expeditions in Wallacea?

Firstly, is the geographic isolation created by the restriction of land bridge formation by the deep-water channels during the last glacial maximum. More than half of the hotspot's mammals, 40 percent of birds and 65 percent of amphibians do not occur outside the hotspot. Another imaginary line can now be drawn through the centre of Wallacea, running North to South, called Weber’s line that represents the point at which the community composition is approximately 50:50 in its influence from either Asia or Australia/New Guinea.As aforementioned the Wallacea region has very high levels of endemism, where a species is unique to a given geographical location, and this is owing to multiple factors.
Well, we’ll come on to that.

The dark grey regions indicate the continental shelf less than 125m deep – the area that was exposed to create land bridges during the last glacial maximum. This line was later named Wallace’s line in honour of its discoverer.

The Wallacea region however remained as a collection of islands much like it is today thanks to a series of deep-water channels that prevented any land bridge forming to join them up to either Sundaland or Sahul. Strengthening Ridge-to-Reef Natural Resource Management in Seram-Buru Corridor What is potentially more important however is that Wallacea is home to so many unique species found nowhere else on earth, has many areas of tropical forest that remain virtually untouched and uninfluenced by humans and should be something that humankind are rightly proud and defensive of. Map: Conservation Outcomes Wallacea Timor Leste These models were presented during a village exhibition. Wallacea /wɒˈleɪsiə/ is a biogeographical designation for a group of mainly Indonesian islands separated by deep-water straits from the Asian and Australian continental shelves. These deep channels then formed a semi-permeable barrier to any species that couldn’t swim or fly, meaning that Wallacea was essentially geographically isolated for a whole suite of flora and fauna apart from chance colonization events that created a sort of slow bleed of influence of species from either Asia or Australia/NewGuniea. Wallace noticed this clear division during his travels through the East Secondly is the fact that Wallacea is and has been a collection of islands for a long period of time.
Alfred Russell Wallace, the co-discoverer of the theory of evolution by natural selection, first visited the Wallacea region in mid-nineteenth century and noticed that animals which he observed on the island of Bali were significantly different to those on Lombok, despite being separated by only 35km of sea.

The Wallacea region, that area of Indonesia marked by the Wallacea line to the West and the Lydekker line to the East and including Sulawesi, Timor and Lombok, is one of the most biologically interesting areas in the world. Adapted from Keally et. A similar imaginary line, Lydekker’s line which separates Wallacea from New Guinea and Australia, can be drawn along the Eastern most edge of the Wallacea region due to another change in fauna.So why should it be that the Wallacea region should come to have such a unique community of flora and fauna, so distinct from its geographical neighbours? To qualify as a biodiversity hotspot, a region must meet two strict criteria:. Community Capacity Building to Protect Turtle Population through Ecotourism in Buru, IndonesiaChildren received storybooks as part of KSP's awareness program. Wallacea Annual Portfolio Overview, 2018 Kelimutu National Park, Flores Island, Indonesia.© Conservation International/photo by Aulia Erlangga ; It must have 30% or less of its original natural vegetation.In other words, it must be threatened. The long-term monitoring data that Operation Wallacea collects, currently spanning a 20-year period, helps us to better understand the impact of these threats and of course influence effective mitigating actions against them. Why? This group continue turtle conservation efforts in Kaiely Village, after Yayasan Wallacea's project is completed. The islands of Wallacea lie between Sundaland to the west, and Near Oceania including Australia and New Guinea to the south and east. Strengthening Community Based Coastal and Marine Resources Management in Minahasa, North Minahasa, and Talaud Districts of North Sulawesi Province, Indonesia However, the region currently faces a plethora of threats, from illegal logging and hunting to mass deforestation and of course climate change. Indeed, for several islands, such as Sulawesi and Halmahera, the geographic shape and topography has led to intra-island endemics too. Then check them out Kealy, S., Louys, J. and O’Connor, S., 2016. Wallacea Annual Portfolio Overview, 2015 Map: KBAs Eastern Lesser Sundas (Including Timor-Leste) In addition, logging roads allow smallholder agriculture and illegal logging to move in. This has led to endemism on both a Wallacea wide and an individual island scale. 1) including Sulawesi (A), Lesser Sunda (B), and Moluccas islands (C). Unsustainable logging is driven by weak enforcement of regulations on cutting volumes and areas, which is caused by a lack of budget and trained and motivated staff to carry out inspections. The result of this is a gradient across the Wallacea region from communities in the western islands like Sulawesi that have a strong component of Asian origin species to communities in the Eastern islands like Seram that a very strong component of Australian/New Guinean species but with a very high level of endemism across the whole of the region.
