The presence of secondary vegetation derived from tropical deciduous forest is recorded in the lacustrine basin of Pátzcuaro in the Mexican state of Michoacán. It is postulated that this forest, widely distributed at altitudes below 2200 m before the formation of the endorrheic basin, no longer occurs in the region, and some of its dominant trees species were Bursera cuneata, Cedrela dugesii, Euphorbia calyculata and Yucca filifera.
The areas at present covered by secondary vegetation derived from this forest, called “subtropical scrub”, are located mainly along northern and western lakeshores, including the islands, and have an approximate surface of 38 km2 in a narrow altitudinal belt between 2040 and 2140 m. The persistent remnants are fragmented, strongly disturbed, and in evident decline, and as a result appropriate conditions for the regeneration of the original forest do not seem to exist.
