Comparative Conclusions

Reference

Jeannie's High Trail Transect was located in a damaged forest area.

Project summary: 

To determine whether a system needs repair it must be surveyed.  Many methods of surveying have been developed over the years.  While each of them are effective and important in their own way, just any survey technique could spell disaster in this situation.  The density of a rain forest is generally thick and the density of a damaged forest area is nearly impassable due to the thick undergrowth.  A complete count of every tree in the stand would be very labor intensive and time consuming.  For this reason a modified version of the variable-area transect was chosen.  It combines the flexibility of a variable plot size and a maximum number of stems.  For this reason, the survey technique can be tailored to the project. 

 

Jeannie's Low Trail Transect was located in a secondary forest area.

La Congreja Trail transect was located 50 meters from the trail.
