ResultsThirteen habitat corridors between JCMA were identified; out ofthem, seven were viable and six potential (Tables 2 and 3; Fig. 1),together they comprise an area of 32 695 km2(20 173 km2viableand 12 512 km2potential). There were Protected Natural Areas(PNA, 3296 km2that correspond to 16.33% of the corridors) in fiveviable corridors and in five potential corridors (Tables 2 and 3;supplementary data). Exist records of jaguar in six of the viable cor-ridors and in five of the potential corridors (supplementary data).The minimal width of the viable corridors is 14.25 km and themaximal length is 230 km (Table 2). The minimal width of thepotential corridors is 2.43 km and the maximal length is 320 km.The viable and potential corridors characteristics are shows in thesupplementary data.Twenty-three stepping stones between the Could Forests ofSierra Madre Oriental and the northern Mixe Oaxaca were iden-tified, with extensions between 17 and 1020 km2(total area:2596 km2); the shortest distance between these patches is 1 kmand the longest 23 km (Fig. 2).Six stepping stones from southern Pacific coast to the north ofOlinalá were identified, with extensions from 92 to 1020 km, whichaccount for a surface of 2770 km2. The shortest distance betweenthese is 1 km and the longest is 11 km (Fig. 3).
