Condition of Mangrove Ecosystems in Sungai Apit Siak Distric Based on Standard Damage Criteria and Quality Indicators Mangrove Environment

Abstract

Mangroves are one of the ecosystems in coastal areas that have an important role, but nowadays many are experiencing threats. The purpose of this study was to determine the condition of mangrove ecosystems in Kecamatan Sungai Apit seen from standard criteria for mangrove damage and the indicators of mangrove environmental quality (species association, tree cover, seedling cover and number of seedlings species). This research was conducted in April 2018 in Kecamatan Sungai Apit, Siak Distric. The method used in this research was survey method. Types and density of mangroves were observed at three stations (Desa Lalang, Desa Bunsur and Desa Sungai Rawa) using line transects and plots. The results showed that the condition of the mangrove ecosystem in the coastal area of Kecamatan Sungai Apit based on the standard criteria of damage (Minister of Environment No. 201 of 2004), seen from the group of trees classified as damaged to good with rare to dense criteria, but when combined with a group of sapling, the conditions mangroves in Kecamatan Sungai Apit were classified as good with very dense criteria. Mangrove conditions based on indicators of mangrove environmental quality in the three stations included in the category of high environmental conditions with successively Qe values (mangrove environmental conditions) were 67.96% (Desa'Lalang), 64.37% (Desa Bunsur) and 84.68% (Desa Sungai Rawa).
