Patagonia (South America)

Patagonia Field Work

Kim Taylor looks for lodgepole seedlings in a 10 x 10 meter plot, one of many in the Patagonia field area used to collect data on lodgepole density, size and cone production. Seedlings visible in foreground to left and right of flag (brightest green plants).

Lodgepole seedling

Pinus contorta (lodgepole pine; invasive) and Oreopolus glacialis (cushion plant; native).

Burn Site

Andes and Divisadero Range in background of Pinus ponderosa plantation, at edge of November 2011 fire. Native Nothofagus forest on the right.

Coyhaique Alto

Pinus contorta (lodgepole pine) seedlings stick out above grasses, running almost all the way to the edge of native Nothofagus antarctica forest.

Coyhaique Alto

Heavily browsed Pinus contorta (lodgepole pine) are short and wide though they are ~ 5 - 8 years old. Mountain range in background is the Andes.

Lago Cástor

Pinus contorta (lodgepole pine) plantations ~ 30 yrs old appear in background and on island. Foreground and area around lake was native Nothofagus pumilio forest prior to burn; it was replaced by anthropogenic grasslands - mainly dominated by European species - and is currently invaded by lodgepole pine.

Burn Site

Burn Site is 5 km north of the Coyhaique Alto site. A fire burned 7 hectares November 2011 through predominantly uninvaded native forest bordered by lodgepole pine.

Herbivory

Pinus contorta (lodgepole pine) demonstrates extreme herbivory at the Coyhaique Alto site. Introduced European hare and sheep graze on pine, causing tall trees to lack lower branches and short trees to be shrubby and wide.

Pine Invasion Field Crew

Bruce Maxwell, Kim Taylor and Anibal Pauchard (Universidad de Concepcion, Chile). Coyhaique Alto site.

Coyhaique Alto

Pinus contorta (lodgepole pines). Road marks a break in the trees. To the left of this road is a plantation of pines, and to the right pines invade the steppe.
