I believe that the more we understand nature, the more we can appreciate its beauty. I want to help decode the patterns of nature. Why are habitats found where they are? What makes certain species thrive? What do these ecosystems tell us about the past? Hope you enjoy. youtube.com/playlist?lis...

Habitats - YouTube

How does each habitat function? Why does it occur where it does? How does this understanding affect conservation?

The #EU Deforestation & Forest Degradation Regulation is due to come into force in 2026. It will ban products made using raw materials from deforested areas on the EU market.
To this end, research needs to come up with indicators to differentiate between preserved & degraded forests.

🌳One way of combating #deforestation is to define zones at particular risk. The difficult part is identifying those zones.
