2.6 The study area was classified us<strong>in</strong>g remote sens<strong>in</strong>g <strong>and</strong> GIS. Unsupervised classification<br />

was made us<strong>in</strong>g ERDAS IMAGINE 8.4, whereas supervised classification was done us<strong>in</strong>g<br />

ILWIS. ILWIS assists classification of vegetation (user-friendly) through its feature space.<br />

The two classifications were compared <strong>and</strong> by apply<strong>in</strong>g expert knowledge (<strong>and</strong> tra<strong>in</strong> the<br />

software by tra<strong>in</strong><strong>in</strong>g po<strong>in</strong>ts) collected from field seven major classes were determ<strong>in</strong>ed.<br />

These seven major classes were identified latter as dense forest, bamboo forest,<br />

<strong>in</strong>tensively cultivated l<strong>and</strong>, exposed surface, moderately cultivated areas, wetl<strong>and</strong>,<br />

disturbed forest <strong>and</strong> highly disturbed forest. In Bog<strong>in</strong>da bamboo forest doesnot exist.<br />

2.7 Transect l<strong>in</strong>es were selected by closely exam<strong>in</strong><strong>in</strong>g the classified map especially on<br />

vegetation part (forest l<strong>and</strong>) (see annex V for distribution of transects). Major <strong>in</strong>terest area<br />

for flora assessment <strong>in</strong> <strong>Bonga</strong>, <strong>Mankira</strong> <strong>and</strong> Bog<strong>in</strong>da were vegetated area especially forest<br />

covered l<strong>and</strong>s. Geographical position of transects’ start<strong>in</strong>g po<strong>in</strong>ts were identified <strong>and</strong><br />

recorded <strong>in</strong>to Global Position<strong>in</strong>g System (GPS). Simultaneously azimuth is determ<strong>in</strong>ed<br />

<strong>and</strong> recorded <strong>in</strong> note book.<br />

2.8 st<strong>and</strong>ard data collection formats were prepared.<br />

The study Area<br />

The study area is found <strong>in</strong> Kafa Zone of Southern Nations, Nationalities <strong>and</strong> Peoples Regional<br />

State.<br />

<strong>Bonga</strong> forest is one of the Regional <strong>Forest</strong> Priority Areas (RFPA). It is estimated to cover an<br />

area of 163,000 ha. <strong>Mankira</strong> forest, which is estimated to cover 900 ha, is part of <strong>Bonga</strong><br />

RFPA. Geographically, <strong>Bonga</strong> RFPA is located 07 0 00’-07 0 25’N latitude <strong>and</strong> 35 0 55’-36 0 37’E<br />

longitude.<br />

Accord<strong>in</strong>g to Girma Balcha et al, 2004, Bog<strong>in</strong>da forest covers about 7,500ha. But <strong>in</strong> this study<br />

wider area is considered, 59447 ha. It is adm<strong>in</strong>istratively located <strong>in</strong> Gewata wereda <strong>in</strong> Kafa<br />

Zone. Geographically, the forest is situated between 07 0 20.000` to 07 0 33.400N latitude <strong>and</strong><br />
