plantations between Parrita and the Savegre River. But have you seen the pineapple plantations on the highway between San Isidro and Buenos Aires? These mammoth monoculture planta-tions are responsible for significant bio-diversity and habitat loss (see photos), water and air contamination, and soil erosion.

A menudo uno escucha acerca de las amenazas evidentes que afectan las áreas protegidas como nuestro Corre-dor Biológico Paso de la Danta (CBPD). En artículos anteriores, hemos hablado acerca de la matanza de animales debi-do al aumento del tráfico en la nueva Costanera y acerca de actividades de desarrollo “poco amigables” con la na-turaleza. Otras amenazas comunes que usted seguramente ha escuchado son la caza ilegal, el comercio con fauna sil-vestre (monos y loras) y la tala ilegal y venta de madera de especies de árboles protegidas.

No obstante, los peligros que conoce-mos cambian constantemente. No hace mucho tiempo, si uno le preguntaba a alguna persona preocupada por la con-servación del Paso de la Danta acerca de cuáles eran las amenazas principa-les para el Corredor, la persona hubiera contestado que eran la ganadería y la cacería. Sin embargo, la mayor amenaza para el CBPD en el presente es la frag-mentación ocasionada por el desarrollo indiscriminado y algunos proyectos de infraestructura gigantescos. ¿Quién se hubiera imaginado esto hace 30 años?

Y muchas otras amenazas desconocidas nos acechan sin que tengamos la menor idea de su existencia. Cualquiera de ellas podría convertirse en el próximo desas-tre ecológico de nuestra área. Durante las últimas semanas, la prensa nacional ha publicado varios artículos acerca del interés de grandes empresas agroindus-triales (productoras de piña y aceite de palma africana) en la costa del Pacífico Central y Sur para efectos de expansión. La mayoría de ustedes deben de haber visto las fi-las interminables en las plantaciones de palma que se encuentran entre Parrita y

el río Savegre. Pero, ¿han visto las plan-taciones de piña en la carretera entre San Isidro y Buenos Aires? Estas planta-ciones gigantescas de monocultivos son responsables de la pérdida de una gran cantidad de biodiversidad y vegetación natural (vea las fotos), de la contamina-

ción del agua y el aire y de la erosión del suelo. Es difícil de imaginar ahora, pero algún día podríamos tener uno de estos “desiertos verdes” en nuestro patio y en nuestro jardín.

Por increíble que parezca, la peor ame-naza que existe en el presente para el Paso de la Danta ha circulado en los me-dios escritos desde hace muchos años: un conjunto de proyectos de infraes-tructura eléctrica que incluye por lo me-nos dos represas y tres rutas distintas de líneas de alta tensión que corren pa-ralelas al CBPD o justamente a través de él. ¿Había escuchado esto? Quédese con nosotros… Le daremos más detalles de este tema en próximos artículos.

You often hear about the obvious threats that affect protected areas such as our own Path of the Tapir Biological Cor-ridor (PTBC). In this column, we’ve talked about roadkill on the coastal highway and “ungreen” development practices. Common threats that you’ve probably heard about as well include illegal hunting, illegal wildlife trade (monkeys and parrots), and illegal cut-ting and sale of protected tree species.

But the threats we see – the obvious ones – are always changing. It wasn’t long ago that, if you were to ask any conservation-minded person in the Path of the Tapir what the major threats were and they would have answered: cat-tle ranching and hunting. But now, look around, and the major threat is fragmen-tation from overdevelopment and ma-jor infrastructure projects. Who could have imagined this thirty years ago?
