Range Description

This species has a very patchy distribution in Hispaniola, suggesting that it has declined from a previously more uniform distribution. It has an altitudinal range from sea level to 1,697 m asl (Henderson and Powell 2009). Surveys conducted between 2008-2010 have recorded this frog at 15 geographic localities of the Dominican Republic including Nalga de Maco, San Jos de las Matas, San Jos de Ocoa, Salto de la Damajagua, Diego de Ocampo, La Vega, La Canela, Monte Plata, Sanchez Ramrez, Ebano Verde, Guaconejo, La Humeadora, Bonao, Miches and Los Haitises. These surveys have expanded its area of occupancy (AOO) since its last assessment in 2004 (G. Ross pers. comm. March 2011). However, even considering this expansion, the occupied area (herein taken as a proxy for AOO, although the actual AOO would be more restricted as some sites consist of small ponds beyond the margins of which frogs cannot survive) in the Dominican Republic is estimated to be 1,165 km2 based on field work and presence of suitable habitat (R. Powell pers. comm. February 2012). In Haiti, surveys conducted since 1984 have never recorded this frog from the "North Island" of Haiti (north of Port-au-Prince and the Cul-de-Sac; B. Hedges pers. comm. February 2012). There are only two historical records for the North Island (Schwartz and Henderson 1991), but it is possible that this frog could be extirpated in this area (B. Hedges pers. comm. February 2012). There is some forest on the South Island, in remote patches, where the possible new taxon is found (B. Hedges pers. comm. February 2012). While there is no estimate for its occupied area in this country, based on the current original forest cover (estimated to be 277.5 km2 or 1% of the original forest cover in Haiti, B. Hedges pers. comm. April 2012) and the rate of natural habitat loss experienced by Haiti, suitable sites are projected to disappear within 10-20 years (R. Powell pers. comm. February 2012; B. Hedges, February 2012), so it is expected that this species' AOO will most likely not exceed 2,000 km2. Its current overall range (taken as a proxy for extent of occurrence) is estimated to be 20,636 km2, which evidences a reduction in the area historically demarcated as its range given natural habitat alteration due to human activities (e.g. loss of area in the Valle de Cibao, portions of the eastern lowlands and central uplands east of HW 1; R. Powell pers. comm. February 2012).
