Lachay National Reserve, located in Lima, Peru, protects a unique lomas ecosystem characterized by coastal desert hills that come alive during the wet season from June to October. The reserve is home to diverse plant species like Tara spinosa and Vasconcellea candicans, as well as birds such as the Vermilion flycatcher and mammals like the Sechuran fox. Visitors can enjoy activities like birdwatching and hiking while taking in the stunning landscape. However, the reserve faces threats from unregulated tourism, firewood extraction, and other environmental issues that endanger its integrity.
