madagascar global hotspot
Madagascar: Global Hotspot
  • Centre of diversity (12,000? species)
  • Centre of endemism (80, 90, 90+? species endemism)
  • Critical human pressure on ecosystems/biodiversity

From: Myers et al. 2000

why a catalogue
Why a Catalogue?
  • Provide set of “names in current use”
  • Provide statistics – the “numbers game”
    • How many endemics?
    • Where are they located?
    • Prioritise areas for conservation.
  • Collate dispersed literature, and other information
  • Stimulate research
    • highlight gaps
    • encourage more detailed studies as necessary (Systematics, Ecology, etc.)
  • Framework for present and future efforts to document the flora
  • Address targets of the Global Strategy for Plant Conservation (GSPC)
  • Why now?
    • many new treatments
    • many new collections
    • Urgently needed by end-users in Madagascar
what will the catalogue cover
What will the Catalogue cover?
  • Vascular Plants
  • Madagascar only (not Comoros)
  • Native species
  • Naturalized species
  • Modern Family alignments
what will the catalogue contain
What will the Catalogue contain?
  • Nomenclature and Types
  • Synonymy
  • Habit
  • Habitat
  • Distribution (Bioclimatic, Provincial, Protected Areas)
  • Conservation Status and Rarity
what will the catalogue look like
What will the Catalogue look like?
  • Printed version
  • Web-based database

how will we produce the catalogue
How will we produce the catalogue?
  • Review existing taxonomic treatments – assess Taxon
    • Recent Flora or Monograph
    • Old Flora or Revision – new material available
      • substantial revision required
      • minor amendments required
    • No revision available
      • Revision currently in progress
      • Worldwide Monograph
      • African / Mascarene revision(s) available
      • literature of individual species descriptions.
how will we produce the catalogue21
How will we produce the catalogue?
  • Capture existing “good” treatments
  • Undertake minor revisionary work
    • Produce synoptic revisions (see examples of Mimusops and Desmostachys)
    • Describe individual new species
    • Nomenclature, (Nomenclatural Notes)
  • “Find” contributors currently working on groups
  • Mentor students

Flore de Madagascar – a basis

What has been done?

178 families out of 222 (80%) treated in full

Some treatments over 50 years old

  • Some older flora volumes replaced by new revisions, e.g.
    • most endemic families
    • Arecaceae
    • Iridaceae

of the remaining 44 non-treated families, some modern treatments are available, notably Fabaceae

  • other non-treated families, some flora treatment /revisions are in advanced stages of preparation/publication, including parts of some large families e.g.
    • Apiaceae – Euphorbiaceae (in part)
    • Araliaceae – Rubiaceae (in part)
    • Asclepiadaceae

Flore de Madagascar

What remains largely “untouched”?

  • small families, e.g.
    • Rosaceae
    • Geraniaceae
  • large/medium-sized families, e.g.
    • Ericaceae
    • Poaceae
  • parts of some large families, notably
    • Euphorbiaceae
    • Rubiaceae
    • Acanthaceae
what have we done so far
What have we done so far?

CONVOLVULACEAE (Fl Mad 2002)  minor changes

  • Synoptic Revisions completed
    • Endemic families, e.g. SARCOLAENACEAE
    • Other out-dated flora treatments, e.g. Buxus
  • Synoptic Revisions in progress
    • Endemic families, e.g. DIDYMELACEAE
    • Other out-dated flora treatments, e.g. Brexia,Desmostachys, Mimusops, Tacca, Xerophyta,
  • Revision / Flora treatment of small families in progress
    • GERANIACEAE
    • ROSACEAE
reflections
Reflections

12,000 spp. may still be an underestimate for the total vascular plant flora of Madagascar

In 1959 the number of species recorded from Madagascar was estimated at 7,900 (Humbert)

By 1992 the increase was estimated at 1445 (18%), giving a total of 9345 (Phillipson)

The rate of adding species seems to have increased, are we now adding 74% to 1959 levels across the board?

If so, available figures suggests a total flora of 13,700 species!

Species endemism still looks to be over 90% in many taxa

Hopefully we will have a more reliable estimate in 5 years time!

The first edition of the Catalogue will be a starting point

Later editions may include other data: what?
