Abstract. Safe’I R, Latumahina FS, Dewi BS, Ardiansyah F. 2021. Short Communication: Assessing the state and change of forest health of the proposed arboretum in Wan Abdul Rachman Grand Forest Park, Lampung, Indonesia. Biodiversitas 22: 2072-2077. Forest health is the fundamental of sustainable forest management. As such, forest health needs to be continually monitored and maintained. This study assessed the state and change of forest health of the prospective arboretum in Wan Abdul Rachman Grand Forest Park (Tahura WAR), Lampung, Indonesia, aiming that the arboretum can serve for integrated conservation and education forest (Tahura War). This research used the Forest Health Monitoring (FHM) method by combining the parameters of vitality (i.e., tree damage and tree crown condition) and biodiversity (tree species diversity) across four Forest Health Monitoring plot clusters. The results showed there was a change in the state of forest health of the prospective arboretum in Tahura WAR. The first measurement showed that 50% of plot clusters had a status of bad, while 25% was moderate and 25% was good. The results of the second measurement showed that 50% of plot clusters had a status of moderate, while 25% was bad and 25% was good. This finding suggests that the prospective arboretum experienced changes toward better conditions in health status. Even so, it is still necessary to carry out regular forest health monitoring activities to determine trends.

AbstrakPenelitian bertujuan untuk mengkaji respon semut terhadap kerusakan habitat akibat kehadiran manusia dalam hutan lindung Sirimau Ambon. Penelitian dilaksanakan dari bulan Juni 2011 hingga Juli 2012. Respon semut diketahui dengan pendekatan kekayaan, kelimpahan, keragaman, frekuensi dan tanggap fungsional terhadap kerusakan antropogenik dalam hutan lindung melalui metode line transect. Parameter tambahan yang diamati adalah faktor iklim mikro, sifat fisik dan kimia tanah. Hasil penelitian menemukan 23 spesis semut, 16601 individu, kelimpahan spesis tertinggi sebesar 0,158, frekuensi 32,44 % dan indeks keragaman sebesar 2,92 yang tergolong sedang. Kelompok fungsional semut terbagi menjadi kelompok oppurtunist (1 spesis), generalized myrmicinae (1 spesis), specialis predator (4 spesis), tropical climate specialis (6 spesis), dominant dolichoderinae (4 spesis), subordinate camponitini (6 spesis) dan criptic species (4 spesis). Faktor antropogenik yang menyebabkan kerusakan habitat hutan lindung yakni pembukaan wilayah hutan, penebangan pohon, pembakaran hutan, perladangan berpindah dan pembangunan fisik akibatnya terjadi fragmentasi dan degradasi habitat yang diikuti dengan ketidakseimbangan lingkungan dan komponen ekosistem.

The objective of field study was to study the response of ants to forest damage due to presence of human activities in Sirimau Conservation forest, Ambon. The respons of ants was analyzed based on their richness, abundance, diversity, frequency and functional response to anthropogenic damage by used of line transecting method. Secondary parameters measured were local microclimate as well as soil physical and chemical characteristics. The study found 23 species of ants and 16,601 individual ants in the forests; the highest species abundance was 0.158, while frequency and diversity index was 32.44% and 2.92 each and were classified as moderate. Functionally ants consisted of oppurtunist (1 species), generalized myrmicinae (1 species), specialist predators (4 species), tropical climate specialists (6 species), dominant dolichoderinae (4 species), subordinate camponitini (6 species) and criptic species (4 species). Anthropogenic activity contributed to forest habitat destruction through forest opening, logging, forest fires and shifting cultivation. Anthropogenic damage in secondary forest caused fragmentation and degradation, followed by inbalance of environment and ecosystem components

The experiment was conducted at residential areas Sirimau forest with three sampling methods, which were hand collecting, bait trap (sugar and tuna) and pitfall traps from July to September 2011. The study aims to determine abudance of ants in residential areas in Ambon Sirimau Protected Forest areas. The results of study found 16 species of ants in total reaching 14.913. The most dominant types are Odontoponera denticulata, Pheidole megacephala, Technomyrmex albipes, Tetramorium simillimum, Tetramorium bicarinatum, Tapinoma melanocephalum, Paratrechina longicornis and Anoplolepis gracilipes. Total abudance of ants is 2.789 classified as moderate by spread of number of individual spread and of community stability. The abudance of ants is strongly influenced by light intensity, temperature, humidity, wind, water and season. Difference of temperature micro, light climate, humidit, interspecific competition, availability of variety of food sources, habitat quality and human activities also affect the abudance of ants. Another finding showed invasive ants, they were Soleonopsis geminate, Paratrechina longicornis and Anoplolepis gracilipes. Keywords: Abudance of ants, invasive species, protected areas, settlement areaAbstrakPenelitian dilaksanakan pada areal pemukiman dalam Hutan Lindung Sirimau dengan tiga metode pengambilan sampel yakni hand collecting, bait trap (umpan gula dan  ikan tuna) dan pitfall trap dari bulan Juli hingga september 2011. Penelitian bertujuan mengetahui keragaman semut pada areal pemukiman dalam kawasan Hutan Lindung Sirimau Ambon. Hasil penelitian menemukan adanya 16 jenis semut dengan total individu mencapai  14.913. Jenis–jenis yang sangat dominan dalam kawasan yakni Odontoponera denticulata, Pheidole megacephala, Technomyrmex albipes, Tetramorium simillimum, Tetramorium bicarinatum, Tapinoma melanocephalum, Paratrechina longicornis dan Anoplolepis gracilipes. Total keragaman jenis semut 2.789 tergolong sedang dengan penyebaran jumlah individu semut dan tingkat kestabilan komunitas sedang. Keragaman semut dipengaruhi oleh intensitas cahaya matahari, suhu, kelembaban, angin, air dan musim. Diduga perbedaan suhu mikro, iklim, cahaya, kelembaban, pola makan, kompetisi interspesifik, variasi ketersediaan sumber makanan, kualitas habitat dan aktivitas manusia yang memengaruhi keragaman semut dalam areal pemukiman hutan lindung Sirimau Ambon. Ditemukan 3 jenis semut yang invasif yakni Soleonopsis geminate, Paratrechina longicornis dan Anoplolepis gracilipes.
