Burung Maleo (Macrocephalon maleo) merupakan satwa endemik dan dilindungi karena keberadaannya yang terancam punah, sehingga dikategorikan endangered oleh IUCN dan termasuk appendix I CITES. Tujuan utama penelitian ini adalah mengetahui dugaan populasi dan perilaku bertelur burung maleo. Metode yang digunakan adalah consentration count dilakukan pada 2 lokasi stasiun pengamatan yaitu sarang bertelur dan sarang tidur yang meliputi data perjumpaan langsung (visual) seperti waktu, lokasi, jumlah individu, nisba kelamin dan aktifitas satwa dan data non visual meliputi jumlah sarang dan produksi telur, sedangkan untuk pengamatan perilaku bertelur menggunakan metode Focal Animal Sampling. Pengamatan di habitat sarang peneluran diperoleh dugaan populasi burung maleo sebesar 2 individu/pengamatan dengan kepadatan populasi 8,57 individu/ha. Sedangkan Non visual dihabitat sarang peneluran ditemukan 1 telur burung maleo. Pada pengamatan perilaku bertelur, teramati 5 perilaku burung maleo yang teramati selama berada dilokasi bertelur yaitu observasi, menggali, bertelur, menutup lubang, dan membuat lubang tipuan. Durasi bertelur burung maleo selama berada dilokasi bertelur berlangsung selama 1-3 jam.

Hutan Lindung Sarambu Alla merupakan kawasan hutan negara yang terletak di Kecamatan Sabbang Kabupaten Luwu Utara. Dalam rangka mendukung tujuan dan fungsi kawasan sebagaimana tersebut di atas, maka dibutuhkan berbagai informasi dasar terkait dengan potensi yang terkandung di kawasan tersebut. Salah satu informasi yang terpenting adalah informasi mengenai potensi dan keanekaragaman spesies tumbuhan. Penelitian ini akan sangat berguna bagi upaya pengelolaan dan pengembangan Keanakeragaman Hayati dan Ekosistem dalam rangka melestarikan keanekaragaman sumberdaya plasmanutfah tumbuhan lokal, endemik, dan langka khususnya yang berasal dari wilayah Luwu Utara atau endemik Pulau Sulawesi secara umum, serta pengembangan potensi obyek daya tarik wisata alam yang terkandung di dalamnya untuk pemanfaatan wisata alam atau ekowisata.  Kegiatan ini diselenggarakan melalui explorasi spesies tumbuhan akan dilakukan secara purpossive dengan menggunakan sistem plot tunggal berukuran 20 m x 20 m.  Berdasarkan hasil analisis vegetasi di Kawasan Hutan Lindung Sarambu Alla menunjukkan bahwa terdapat 64 spesies yang ditemukan pada 25 plot pengamatan. Terdapat 32 spesies dengan habitus pohon memiliki potensi sebagai kayu komersial, bahan bangunan rumah, dan buahnya dapat dikonsumsi serta tumbuhan obat. Spesies tersebut bisa dijadikan model pengembangan baik ditanam pada lahan milik masyarakat, ruang terbuka hijau dan pada lahan atau kawasan hutan yang telah rusak atau terganggu.

Sulawesi island is a unique island among other islands in indonesia. This research aims to find out the social interaction behaviour of Dare Black Monkey (Macaca maura) in the Lejja natural tourism park. This animal is an endemic in Sulawesi island, located in South Sulawesi Province and categorixed as an endangered species by the IUCN, therefore its existence must be protected. The method was used field observation and focal animal sampling. The object was detremined in 15 Macaca maura based on age and sexuality in a group.Social interaction behaviour was recorded, namely the behavior of playing, grooming, coitus, conflict. Based on the results that the high social behaviour frequency of playing activity was owned by the young male (72 times) and the children (56 times), as well as grooming by young male and children  have the highest frequency (31 times).  Frequency of coitus and agonistic behaviours was owned by adult male with 14 times and 5 times respectively.However, the longest time proportion of playing was used by children with  10.602 second (62,01%),while the total and time percentage of coitus have the lowest value (240 second or 2,11%  and 300 second or 2,58% perspectively) by adult ages.Kata Kunci :, Macaca maura, social behavior, grooming, Lejja natural tourism park

Aren (Arenga pinnata) is a type of palm where almost all of its parts can be utilized, starting from the roots, stems, leaves, flowers, and fruit. Based on the growth rate of sugar palm can show the pattern of distribution using the Morisita index formula. The distribution pattern is a series that has settled on a symptom itself between individuals, which can be divided into three, namely uniform (regular), random (random), and clustered (clustered). This study aims to determine the distribution pattern of the sugar palm (Arenga pinnata) population based on the growth rate. This research was carried out in Sangtandung Village in July 2021. The data collection method used a purposive sampling technique by placing plots in an area with a sugar palm population following the river body 200 meters long. The distribution pattern of sugar palm based on the growth rate was analyzed using the Morisita index formula. Based on the Morishita index, the study results obtained a pattern of palm sugar distribution based on the growth rate, namely seedlings, saplings, trees with clustered patterns, and poles with uniform patterns.

Information regarding the potential and dominance of local plant species in the Sassa Village Protection Forest, North Luwu Regency is still limited. In fact, there are fewer and fewer local plant species that are used by the community, this is indicated by the difficulty of obtaining local plant seed sources. This difficulty is due to the lack of local parent plants in this area, for this reason it is necessary to study the potential of local plants and the selection of parent trees for local plant seed sources. The research method by collecting data was carried out using exploratory techniques with the transect method, then the parent tree that had been determined as a seed source stand that had met the criteria as a parent tree was given a coordinate point. Then the scoring was carried out on tree height (T), tree diameter (D), branch-free height (Tbc), trunk straightness (KB), trunk surface (PB) and tree health condition (KK). The results of this study obtained 16 types of plants with the highest T score of 20, 16 species of plants with the highest D score of 30, 33 species that had the highest Tbc score of 15, and 3 types of plants that had the highest KB+PB+KK score of 20. There were 18 species with a total score of >60 that met the highest criteria as well as from the various genotypic characteristics that had been observed.
