Characterization of the Forest Floor in Stands along a Moisture Gradient in Southern New Mexico1
- A. G. Wollum2
Forest floor properties of stands along a moisture gradient from dry, represented by a piñon-juniper stand (Pinus edulis Engelm—Juniperus scopulorum Sarg.), to wet, represented by a white fir stand (Abies concolor [Gordon & Glend.] Lindl.), were studied. Dry weights and amounts of nutrients were directly related to the moisture gradient. For example, dry weights of the forest floor increased from 9.4 to 80.8 metric tons/ha from the dry to the wet end of the moisture gradient, respectively. Nutrient concentrations were not related to the moisture gradient with the exception of K. In the more mesic stands sufficient water appears to have been present to allow substantial leaching of K from the forest floor.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
