A ‘Stepping-Stone’ Approach to Endangered Species Release

Optimizing release strategies: a stepping-stone approach to reintroduction (2019) Lloyd et al., Animal Conservation, 22.

The Crux

Restoring endangered species through breeding the species in captivity has become common practice over the last century, and has led to the successful recovery of many species. But the process is complicated, as there are always dangers inherent in releasing species that have become used to captivity back into the wild.

This week’s researchers wanted to test a new approach: rather than releasing species directly back into an area where they have disappeared from, they wanted to first release individuals into an already-occupied habitat patch, where predators and prey were present but the species had a high survival probability. This would be a stepping stone before a second release, intended to restore a population in a new area.

Privately protected areas provide key opportunities for the regional persistence of large‐ and medium‐sized mammals (2018) Clements et al., Journal of Applied Ecology, 56(3), https://doi.org/10.1111/1365-2664.13300

Det Essensielle

Da mennesker slo seg ned i nye områder, bosatte de seg som regel i de mest produktive og artsrike områdene. I dag, mange år senere, er disse områdene fortsatt produktive og i private hender. I dag, derimot, blir flere og flere arter utrydningstruet og vi iverksetter tiltak for å redusere tapet av arter. Et av disse tiltakene er verneområder. Verneområder er områder som er satt til side for å sikre tilstedeværelse av gitte arter eller naturtyper ved å begrense høsting eller annen menneskelig innflytelse. Utfordringen er at dette ofte er kostbart da disse artsrike områdene ofte overlapper med områder som har viktige jordbruk- eller andre naturressursinteresser. Dette resulterer i at vernede områder ofte blir lagt til økonomisk marginale og/eller statseide områder. For å kontre dette kan en inkludere områder tilbudt frivillig av grunneiere. Spørsmålet blir da, hva er verneverdien av de områdene som blir tilbudt? Dette er spørsmålet som Clements og medforfatterne spør seg når jobber med Cape Floraregion i Sør-Afrika .

The Role of Private Property in Conservation

Privately protected areas provide key opportunities for the regional persistence of large‐ and medium‐sized mammals (2018) Clements et al., Journal of Applied Ecology, 56(3), https://doi.org/10.1111/1365-2664.13300

The Crux

When humans settle down in new areas, they usually settled in the most productive and species-rich areas. Now, years later, these productive areas are usually still productive, but often still in private hands. However, today more and more species are facing extinction, and many would be helped by the protection of these areas. Protected areas are areas that are set aside to ensure the viability of certain species by limiting human exploitation of the local natural resources. However, this might be costly, and these hot-spot areas likely overlap with agricultural or other natural resource exploitations, with the result that protected areas are often located to economical marginal and state-owned lands. To counter this, one might include lands offered voluntarily by private owners. But are the lands they’re offering of any conservation value?

Why Do We Only Care If It’s Fluffy?

Species like koalas are cute and fluffy, and thus easy to provide funding for. But how do we save species that are more threatened and less charismatic?

After my recent talk with Marlene Zuk (which we’ll be publishing later this week), I have been thinking more about the species we focus on in ecology and the species we neglect. Dr. Zuk is a specialist on insects, who has remarkably been able to sell the importance of topics as obscure as cricket sex and parasite wickedness to the public (as you can see in her brilliant TED Talk). However this is more the exception than the rule. In ecology, conservationists have traditionally focused on a select few animals. So why do we care about saving the pandas that do not want snuggles (or to get it on), and ignore the native worms that are being replaced by invasives? Can we change what the public cares about, and ask them to focus more on the role of a species in an ecologic system?
