  1. Retain buffer zones around core habitat

    A replicated, controlled study in 2008–2009 of golf course ponds in Ohio, USA (Puglis & Boone 2012) found that unmown buffers around ponds had mixed effects on tadpole survival and mass depending on frog species and site. When reared in ponds with buffers, Blanchard’s cricket frog Acris blanchardi tadpoles had significantly greater survival (0.5 vs 0.2) and mass (0.4 vs 0.3 g) at one site of three sites and green frog Rana clamitans tadpoles had significantly lower survival (0.1 vs 0.4–0.7) and mass (3.0–4.0 vs 1.5–2.5 g) at two sites. Mass was significantly lower at one buffered site for green frogs (0.5 vs 2.5 g). Rate of development did not differ in buffered and unbuffered ponds. In 2008, 40 green or cricket frog tadpoles were placed in ten enclosures in two ponds at three sites, one pond with and without a 1 m unmown terrestrial buffer zone. Enclosures were monitored daily for metamorphs.
