The research aims describe and compare the condition and management of the mangroves at Deli Serdang regency. The research aims describe and compare the condition and management of the mangroves at Deli Serdang regency. The research study was conducted in 9 mangrove villages at the coastal region of Deli Serdang regency. The methods used the square line with a line 10 m x 60 m sizes by vertical sea side ways for each village. The seedlings sub size 2 m x 2 m square, the saplings sub size 5 m x 5 m square, and trees level sub sizes 10 m x 10 m. The parameter analysis was important values index, diversities index, profile diagram, the mangrove thickness and salinities. The result, showed that mangrove vegetations was dominated by Avicennia marina (api-api hitam) and followed by Excoecaria agallocha (butabuta) and Avicennia alba (api-api putih). The diversities mangroves of the coastal region Deli Serdang regency are still low. The thickness and the thinness of mangrove forest were found in Paluh Kurau (500 m) and Rugemuk (20 m), respectively. The mangroves villages with the highest canopy wide were in Karang Gading (78,99%), Tanjung Rejo (63,76%), while the lowest one were in Paluh Sibaji (20,58%) and Rugemuk (26,43%). The highest salinity were found at sub districts of Labuhan Deli and Hamparan Perak, while middle salinity at sub district of Percut Sei Tuan, while of district of Pantai Labu the salinity were from low level to middle. Base on the analysis of the vegetation closeness and canopy width, the condition of coastal region of Deli Serdang regency mangroves were destroyed. |
