COMPOSITION ASSESSMENT UNDERSTORY FLORA

OF JABONGA, AGUSAN DEL

NORTE

JONI REY CAMPILAN

• Vegetation has been widely used to describehabitat characteristics, water quality and make predictions about the presence and composition of the surrounding communities (Appelgren and Mattila, 2005).

• Last survey of the vegetation surrounding Lake Mainit: PAWB, 1997

BACKGROUND OF THE STUDY

This study sought to:

1. Collect, classify, and identify understory plants of Jabonga, Agusan del Norte.

2. Assess the composition and distribution of the identified specimen in terms of Density, Relative Density, Frequency, Relative Frequency, Dominance, Relative Dominance, and Species Diversity.

3. Evaluate the conservation status of plants documented.

1.1 OBJECTIVES OF THE STUDY

The study serves as

BASELINE information on composition of

understory plants in Jabonga, Agusan del Norte.

AID to the developing core objectives for the

conservation monitoring and decision making of the area.
