The Asa Wright Nature Center was established on 22 Dec. 1967, with the Royal Bank Trust Company (Trinidad) Limited appointed as Trustee.

The Trust was meant to protect Springhill "in perpetuity", developing its agriculture in an "ecologically sound" way while facilitating its "scientific and educational" potential.

Holmes added two bathrooms, a water supply, septic tank, generator, two room guest house, and a bathing pool at the foot of the waterfall.

After World War II, Newcome and Asa Wright bought all of the property except the ten acres containing the guest house, pool and waterfall.

Bird species at the nature centre include purple honeycreeper, tufted coquette (a hummingbird), tropical mockingbird, and oilbird (a nocturnal fruit eater).
