Many of the world’s primates are threatened, so conservation is at the heart of PSGB’s work.
Money donated by PSGB members directly and that raised by selling goods at meetings is, each year, donated to a conservation cause selected by the Conservation Subcommittee and approved by Council. Different geographical areas 'take turns' each year, such as an African-based conservation project is supported one year, followed by a Central/South American-based org, then a Madagascar-based project, followed by an Asia-based org, and so forth.
For 2025, we have selected a conservation cause that operates in Central or South America.
Conservation Cause 2025

The Mountain Marmoset Conservation Program - MMCP, Brazil
The Mountain Marmoset Conservation Program - works with two species of endemic marmoset: Callithrix flaviceps the buffy-headed marmoset – IUCN Red-listed as Critically Endangered, and Callithrix aurita, the buffy tufted-eared marmoset, Endangered, in the highly threatened Atlantic rainforest of Brazil (also home to a suite of other endemic primates).
The MMCP is working on 6 main conservation initiatives:
1) Investment into conservation breeding facilities to ensure that free-ranging hybridization doesn't threaten species at risk of extinction;
2) Data collection and analysis to shape and direct decision-making and strategies for conservation;
3) Development of campaign materials to generate and motivate support for the program;
4) Developing and expanding legal protection (municipal laws) using marmosets as focal flagship species, and for raising public awareness;
5) Supporting and facilitating local collaborative efforts where active conservation and research projects exists, and where new ones are being considered; and
6) In-situ conservation management to create areas of exclusion of other invasive marmoset species.

The Society has fundraised over £17,000 total across it's conservation causes! That money goes towards supporting primate conservation and making a positive, tangible difference. This couldn't be achieved without our wonderful members who continually support both the Society and primate conservation.
Below are the previous organisations supported as our conservation cause. Full details on the project, as well as their project posters and total raised, are available to view here.
