Fire in Highland Pine Forests of the Dominican Republic―The Long View

Large forest fires in Valle Nuevo National Park in 2014 and 2015 have increased interest in fire as an ecological force in montane pine forests of the Dominican Republic. Geographer Dr. José Ramón Martínez Batlle estimated using Landsat imagery and GIS that some 4700 ha burned in July 2014 (http://www.geografiafisica.org/2014/07/29/superficie-quemada-incendio-valle-nuevo/), and an additional 1600 ha burned in late April 2015 (http://www.geografiafisica.org/2015/09/25/superficie-quemada-en-valle-nuevo-finales-de-abril-principios-de-mayo-2015/).

Since 1995, when I first visited what is today Valle Nuevo National Park (then, Valle Nuevo Scientific Reserve), as a guest of the Moscoso …

We examined pollen, pteridophyte (ferns and fern-allies) spores, and charcoal in a 5.6 m long sediment core from Lago de las Morrenas 1, and charcoal in a 1.1 m long sediment core from Lago Chirripó, to reconstruct postglacial vegetation and fire history in the Chirripó páramo. Lago de las Morrenas 1, the largest lake in the Valle de las Morrenas of Chirripó National Park, is presently surrounded by treeless páramo vegetation and has apparently been so since deglaciation approximately 10,000 radiocarbon years ago. Pollen spectra suggest no pronounced changes in vegetation since ice retreat. Pollen percentages for Gramineae and other …
