Sebagai bagian dari kebun raya dunia, Kebun Raya Indonesia (KRI) memiliki tanggung jawab untuk melaksanakan upaya konservasi tumbuhan dan penelitian di Indonesia. Pada kenyataannya, empat kebun raya yang dikelola oleh LIPI baru mampu mengkonservasi sekitar 21,5% dari seluruh tumbuhan terancam kepunahan Indonesia. Oleh karena itu, diperlukan pengembangan Kebun Raya Daerah (KRD) untuk mengkonservasi tumbuhan pada tiap daerah di Indonesia. Makalah ini bertujuan untuk mengetahui capaian KRD dalam konservasi tumbuhan dan menentukan strategi pengelolaan koleksi tumbuhan pada tiap KRD, terutama dalam mendukung pencapaian Target 8 GSPC. Pada akhir 2012, KRI bersama KRD telah berhasil mengoleksi 24% dari tumbuhan terancam kepunahan Indonesia dan telah berhasil melakukan perbanyakan 25% dari tumbuhan terancam kepunahan itu (termasuk koleksi di pembibitan). Beberapa strategi untuk D. W. Purnomo et al. Pengembangan Koleksi Tumbuhan Kebun Raya Daerah 112 pengembangan koleksi KRD antara lain: penguatan sistem data base koleksi; pengembangan koleksi tumbuhan di setiap KRD dengan mengacu pada IUCN Red List dan jenis unggulan lokal; dan penentuan spesies prioritas untuk konservasi.

ABSTRAK
As a member of the International Association of Botanic Gardens (IABG), Indonesian Botanic Gardens (IBG) has responsibilites to conduct plant conservation efforts and research in Indonesia. In fact, four botanic gardens managed by the Indonesian Institute of Sciences were only able to conserve approximately 21.5% of the Indonesian threatened plants. Therefore, it has been important to develop local/regional botanic gardens (L/RBG) throughout Indonesia in order to conserve the plant diversity. This paper aims to review and highlight the L/RBG achievements in plants conservation and to establish management strategy of plants collection in each region, especially in achieving the Target 8 of the GSPC. At the end of 2012, IBG and L/ RBG has collected and managed 24% of the Indonesian threatened plants and succesfully cultivated 25% of the Indonesian threatened plants (including in the nursery collections). Some strategies developed for the L/RBG plants collection development include: strengthening collection management and data base; developing and enriching plants collection in each L/RBG with reference to the IUCN Red List and local flagship species; and setting the priority species for conservation policy and actions.

Mount Sekincau is a part of Bukit Barisan Selatan National Park (BBSNP) that has less been explored. It is situated at between 1100 to 1719 m above sea level. This area included in the category of lower montane rain forests. A vegetation analysis has been conducted to determine the tree structure variation and composition of trees in Mount Sekincau BBSNP. Sample plots were randomly chosen (purposive random sampling) at five locations which consist of 10 plots sized 50 x 50 m2 (0.25 hectares). There were 32 families 59 genus and 89 species with a density of 253 ind/0.5 ha. Mount Sekincau area has an airly good condition, this is indicated by the average value of diversity index (2.67) and evenness index (0.47). Trees often found in this area are members of family Lauraceae, Fagaceae, Euphorbiaceae, Dipterocarpaceae, Myrtaceae and Rubiaceae. Quercus blumeana Korth. (kayu pasang) is dominating and important species (IVl = 27.18%) and has a wide distribution in Sekincau. The forest in this area has an important role to support life and the environment. Therefore, managers of BBSNP can improve care and maintenance. Moreover, Sekincau area directly adjacent to residential areas, so that the necessarily sustainable management on an ongoing basis to meet the needs of the surrounding community.

Areal konservasi yang didedikasikan untuk koleksi dan pertukaran bahan tanaman disinyalir menjadi sumber gulma bagi wilayah di sekitarnya. Tujuan dari penelitian ini adalah mengindentifikasi dan mengevaluasi gulma ruderal invasif di Kebun Raya Bogor (KRB). Observasi dilakukan untuk mengidentifikasi spesies gulma, menentukan tingkat invasif, dominasi gulma, dan penyebarannya di dalam KRB. Gulma diamati pada setiap vak (petak) termasuk asosiasinya dengan tanaman koleksi. Data pengendalian gulma dan kematian tanaman koleksi dianalisis kaitannya dengan keberadaan gulma. Penyebaran gulma di luar areal KRB diamati secara transek mengikuti alur sungai dan jalan raya. Hasil menunjukkan bahwa terdapat tujuh gulma invasif yaitu Cecropia adenopus (Cecropiaceae), Cissus nodosa Blume (Vitaceae), Cissus sicyoides Blume (Vitaceae), Dioscorea bulbifera L. (Dioscoreaceae), Ficus elastica Roxb. (Moraceae), Mikania micrantha H.B.K. (Asteraceae) dan Paraserianthes falcataria (L.) Nielsen (Fabaceae). Ketujuh gulma tersebut menginvasi pada 41 famili dari total 215 famili yang ada di KRB. Enam spesies yaitu C. adenopus, C. nodosa Blume., C. sicyoides Blume., D. bulbifera L., M. micrantha H.B.K. dan P. falcataria (L.) Nielsen pada awalnya adalah koleksi introduksi di KRB sedangkan F. elastica Roxb. merupakan spesies asli setempat. Ada dugaan kuat bahwa penyebaran gulma invasif di KRB karena pengaruh angin, burung, kelelawar, pengunjung dan aliran air. Semua gulma yang ada, juga ditemukan di luar areal KRB. Mengingat pengaruh gulma tersebut terhadap tanaman koleksi di KRB cukup merugikan, oleh karena itu, perlu ada langkah pengendalian jangka panjang yang komprehensif terhadap gulma tersebut baik di dalam maupun di luar kawasan KRB dengan melibatkan otoritas setempat.

Kontribusi emisi gas rumah kaca, yakni karbondioksida (CO2) dan terutama methane (CH4) dari ekositem lahan basah (wetlands) termasuk yang terbesar. Interaksi antara tipe vegetasi, factor abiotik, dan pegolahan lahanadalah penting dalam perhitungan fluks karbondioksida dan methana dari suatu ekosistem. Dalam penelitian ini, pengukuran terhadap fluks gas karbondioksida, metahana, karakter tanah, kelembapan udara dan suhu serta komposisi vegetasi di ekosistem rawa pasang surut asin (salt marsh) dan rawa payau (brackish marsh) dilakukan di pulau Terschelling, Belanda. Penelitian ini bertujuan untuk mengetahui pengaruh komposisi tumbuhan model pengelolaan (a.l. penggembalaan/grazing atau pembabatan/mowing) terhadap emisi gas karbondioksida dan methana dari ekosistem rawa. Komposisi vegetasi di dua tipe rawa berbeda. Keragaman jenis dipengaruhi oleh kegiatan pengembalaan; jumlah jenis di tapak rawa payau yang mengalami penggembalaan adalah 39 jenis sedangkan yang tidak mengalami penggembalaan adalah 31 jenis. Fluks karondioksida di rawa asin hampir sama besarnya dengan yang ada di rawa payau. Fluks methana rawa asin lebih rendah dibandingkan fluks methane rawa payau. Di daerah rawa payau, penggembalaan meningkatkan emisi gas methana.

This article examines decolonial approaches to the nature of botanical gardens in Indonesia in the artworks of nine artists featured in the exhibition On the nature of botanical gardens: contemporary Indonesian perspective at Framer Framed, Amsterdam in 2020. Zico Albaiquini, Arahmaiani, Ade Darmawan, Edwin, Samuel Indratma, Lifepatch, Ipeh Nur, Elia Nurvista, and Sinta Tantra presented works which confronted the coloniality of botanical gardens. This article provides a historical reading of the content matter of the artworks presented from a decolonial standpoint as conceptualized by Aníbal Quijano, Walter Mignolo, and María Lugones. The article will demonstrate that the artists have applied various strategies and methods to uncover, criticize, and decolonize botanical gardens and their role in empire-building, knowledge development, and the exploitation of nature. Some artists take this farther and develop a decolonial aesthesis or sensibility in order to re-appropriate Indigenous knowledges and ways of being which were silenced and erased by coloniality.
