Introducción:

Todos sabemos que el agua es necesaria para vivir: especialmente para las plantas. Por consiguiente, si el suelo tiene una buena capacidad de retención del agua, se esperaría que pudiera sustentar una comunidad de plantas considerable.

Introducción:

Mientras más ligero entre el agua en el suelo, menos probable será que corra por tierra, y cause erosión. El agregado es la estructura básica del suelo, incluyendo las partículas de suelo (arena, cieno y arcilla) y el humus que se encuentra en el suelo.

Introducción:

Esta actividad utiliza una cinta métrica especial que convierte la circunferencia de un árbol en diámetro. Esta cinta permite a los silvicultores dar rápidamente con el diámetro de un árbol sin recurrir al cálculo, lo cual representa un gasto de tiempo en el campo.

Remote sensing is one of many techniques that forest managers and scientists use to study ecological processes in forest ecosystems. “Remote” simply means that the forest is being studied or measured from a distance. For example, airplanes and satellites, often equipped with radar and thermal scanners, can be used to take photographs, capture video recordings, or take sophisticated measurements of forested landscapes.

Scientists classify tree size by measuring tree diameter. The investigators will measure the diameter of trees, determine tree crown class, calculate average species densities, calculate average tree diameters, and calculate size classes of the trees.

Ecological complexity depends upon species diversity and the structure of species interactions. Complex ecosystems are hierarchically controlled, characterized by non-linear feedback loops, and exhibit patterns that can be observed over many different spatial and temporal scales.
