Photo of Leaf decomposition baskets hold apart the leaf litter layers in a hurricane simulation experiment in the Luquillo Experimental Forest of Puerto Rico. Leaf decomposition and nutrient cycling were studied in decomposition baskets with screens placed between layers to measure decay rates, nutrient movement between layers, phosphorus retention, and number of mushroom fungal connections between litter layers. Placement of green ‘hurricane' leaves (top layer) over freshly fallen senesced leaves (middle layer) and the forest floor (bottom layer) protected the underlying litter and decay fungi from drying when the canopy was opened by trimming tree branches.

Leaves Left on the Ground After Storm Damage or Logging Lead to Faster Forest Recovery

Opening a forest, whether by storm damage, tree harvesting or thinning, dries the forest floor and reduces the ability of the litter layer to re ...

Jean Lodge measuring the extent of mushroom mycelia on the forest floor three months after a simulated hurricane treatment in which limbs and leaves were trimmed from the canopy and deposited on the forest floor in the Luquillo Experimental Forest of Puerto Rico.

Opening the Forest Canopy Slows Leaf Decomposition and Nutrient Cycling

Forest canopies are opened by thinning, logging operations, and storms. Results of a simulated hurricane experiment showed canopy opening had th ...
