An
Initiative to Increase Knowledge of and Monitor Changes in Species of
Temperate Climbing Plants
|
|
Trees in temperate forests are relatively well
known after centuries of intensive study of their reproductive biology,
logging potential, regeneration, and diseases. In contrast climbing plants,
lianas and vines, are relatively poorly understood in temperate forests.

Half Hectare Plots in Temperate Forest Ecosystems
|
|
Using teams of 3-4 people,
we select a 0.5 hectare plot (50 x 100m) in forested ecosystems that show
little influence from logging or other human disturbance (e.g., vine
"management", extensive trails, farming, etc. ) in the past 75
years. The site is gridded into 10 x 10m cells. Each cell is censused for ALL
climbing plants (vines, lianas) in the cell. For stems larger than 0.5cm at
1.3m above their rooting position, stems are mapped to exact position within
the 10 x 10m cell, stem diameter is noted at two positions, species are identified,
and the tree (or stump) on which the climber is growing is identified. For
stems smaller than 0.5cm at 1.3m above their rooting position, we note the
species as "present" in the cell, but do not take data on abundance
or position within the 10 x 10m cell. CLIMBERS
Census Sites: Green symbols mark established plots; Red symbols are planned
for 2011; Each site may represent more than one 0.5 hectare plot.
