The 55-acre Museum and Zoo compound acts as the "green lung" of Thiruvananthapuram, providing a massive canopy of old-growth trees amidst the urban landscape.
* **Air Quality**: Due to the heavy tree cover within the botanical gardens and zoo, the immediate air quality (AQI) within the compound is notably better than the city average, usually resting in the "Good" to "Satisfactory" range. * **Botanical Wealth**: The grounds feature a spectacular array of indigenous and exotic tropical trees, some dating back over a century. * **Conservation**: The Thiruvananthapuram Zoo has shifted its historic focus from recreation to wildlife conservation, participating in breeding programs for endangered species like the Nilgiri Tahr and Lion-tailed Macaque. * **Sustainability Practices**: The museum complex is gradually integrating solar lighting and stricter plastic-free zones to protect both wildlife and heritage.
