Main project your organisation is involved with, in relation to (sub)tropical biodiversity: 

Biodiversity of the coastal littoral vegetation of Rotuma Island, Fiji The coastal littoral vegetation of Rotuma Island (Republic of Fiji) is very important for its ecological, cultural and medicinal values. A survey was conducted of the entire coast of the island using 50 representative sample sites, to obtain baseline information on the present composition of the littoral flora. Ninety-nine species were identified consisting of seven ferns and 92 angiosperms, of which 16 were monocotyledonous and 76 dicotyledonous. There were 51 families comprising of 80genera, with biodiversity at the generic level being higher than at the species level. Thirty-seven per cent of the total littoral plant species growing along the coast of Rotuma were considered rare or threatened. The main reason for the rarity of these species was identified as the clearance of coastal forests for home building and plantation development. Public awareness programmes should be created to avoid the total loss of these threatened species, many of which have ecological, cultural and medicinal value. http://repository.usp.ac.fj/3123/

Payri, C.E. and N’Yeurt, Antoine de R. and Mattio, L. (2012) Biodiversity, Resources, And Conservation Of Baa Atoll (Republic Of Maldives): A Unesco Man And Biosphere Reserve. Atoll Research Bulletin, 590 . pp. 31-66. ISSN 0077-5630 The present survey was undertaken to provide the first census of the marine flora (macroalgae and seagrasses) of Baa Atoll, one of the 26 Maldivian atolls, and to serve along with the macro-fauna biodiversity inventories for conservation purposes. Species collection and inventories have been conducted at 27 sites covering the widest selection of habitats recognized based on satellite images including islands shorelines, reef flats, faros, patch reefs, passes as well as shallow and deep outer reef slopes. A total of 405 specimens were collected and 176 species representing 10 Phaeophyceae, 58 Chlorophyta, 108 Rhodophyta and two seagrasses were identified. The lagoon patch reefs and the oceanic reef slopes were the most diverse geomorphological habitat types and displayed the highest species richness with 38 spp. All lagoon sites shown a similar richness compared to each other with an average species number of 26 spp, while the deep lagoon floor and the seagrass beds in oceanic-exposed reef flats were the less species-rich habitats. The most common species, occurring at all visited sites, were Tydemania expeditionis and Halimeda minima and the most species rich genera appeared to be Halimeda and Caulerpa. No community structure nor strongly supported species assemblages associated to geomorphological habitat types was found. Previous lists available for other Maldivian atolls listed 208 algal species. Sixty of these records were found in Baa Atoll while 113 of the species recorded in the present study represent new records for the Maldives bringing the total number of algal species to 321. The resulting species list shows that the Maldivian algal flora is typically tropical and most of the species belong to the Indo-Pacific biogeographic province. In this paper, we give a general description of the representative macrophyte communities of Baa Atoll in relation to the geomorphology of reefs. http://repository.usp.ac.fj/5289/

Good practices your organisation could share on tropical and subtropical sustainable biodiversity management: 

Topic: 

Coastal and land management

Purpose: 

To properly manage human uses of coastal areas and forest to minimize impacts on terrestrial and marine ecosystems

Methodology implemented: 

Vulnerability and Adaptation surveys, EIAs, stakeholders consultation, habitat mapping

Existing results: 

Coastal rehabilitation projects, marine protected areas, forest conservation areas (under the REDD+ scheme), Locally Managed Marine Protected Areas (LMMAs)

Good practice & policies your organisation suggests/desires on (sub) tropical biodiversity management.: 

Topic: 

Deep-sea mining

Purpose: 

To put in place proper guidelines for the management and protection of deepwater biodiversity in face of the dangers of commercial deep-sea mining in the Pacific region.

Methodology implemented: 

Stakeholders consultations, V&A assessments, EIAs, Moratoriums

Existing results: 

None so far - a lot of confusion and misinformation among stakeholders
