Butterfly Conservation


A Conversation about Conservation!

Currently, we are living through the Holocene Extinction period ­– the biggest mass extinction event since we lost the dinosaurs 66 million years ago! Whilst we’re not 100 per cent sure what wiped out the dinosaurs and three quarters of the Earth’s animal and plant life all those years ago, we are sure about the number one cause of the Holocene Extinction Event – it’s humans.

A mix of our activities has indiscriminately, directly and indirectly, caused the extinction of over 800 known species since 1500CE. We have only catalogued 1.2 million species and modern estimates predict that 8.7 million might exist, we cannot be sure about just how many we are losing, but it may be as many 150 a day.

Therefore, active help is required. Hanwell Zoo contributes in three ways: Conservation, Education and Community.

For up to date information on our community events please follow us on our social media channels.


Hanwell Zoo holds a number of animals whose numbers in the wild are declining. Bali starling, red-crowned crane, phantasmal poison arrow frog, Azara’s agouti and the hazel dormouse, to name but a few. International efforts are in place to ensure these species are well looked after in captivity, and their numbers kept at sustainable levels.


From thousands of local school children participating in our education programmes every year, to even more visitors enjoying our onsite resources, we pride ourselves on bringing the conservation message to you all. By informing ourselves on the plight of the natural world, we feel more engaged and perhaps more inclined to help.


Community is the essence of our being. Without the support and involvement of the wider community, we would not be able to deliver the services we do. From volunteering, support and participating with events, our community directly sustain our conservation work. To see how you could get involved, click here
