Fulbright > Invasive cattail stand in La Bocana Marsh (Palo Verde National Park). This wetland used to be seasonal (6 month rainy season, 6 month dry season) with very little cattail. It now receives agricultural runoff from nearby rice and sugarcane fields all year long. The result is a very dense cattail stand where the stems reach up to 5 m! These wetlands used to be visited by tens of thousands of birds in the dry season but not anymore.

Fulbright > This is one of the cattail management plots. We've removed the cattail to the right and are monitoring the change in the plant community. The PVC pipes mark the border where we will track the cattail expansion into the plot. Cattails can send their roots horizontally below the soil and send up new shoots. We're measuring how quickly that expansion occurs.

Fulbright > Birds (mostly Black Bellied Whistling Ducks) in Palo Verde Marsh. Between December and April, Palo Verde is an incredible place to visit. The birds that visits the wetlands are awesome, the trees lose their leaves so it's easy to see wildlife (monkeys, coatis, peccaries, agoutis, and much more), and then at the start of the rainy season the trees light up all at once with brightly colored flowers that last for just a couple of days. And the mosquitos (which can be overwhelming in the wet season) disappear.
