the end of lYY8 led to the discovery of several other populations. AS rll tlloWn populatious on

On the strongly degraded island of Santiago only few larger populations of this endemic shrub

are known to have remained (Gomes & al. 1995a). A hitherto unknown large population of sev-

eral hundreds of malurc individuals has been discovered in 1999. The species there grows associ-

ated with Lc~wm/rr/cr r-mrrrcl~lidkc. C~r~r~/~,~/o~~Ittrs glcrher subsp. ~ekrbrr. Sic/errt.t,v/orr nrcrr,vincrrrr

This species. which is similar to Ec/rirrnr /f~/~er~rcJ/~icrtnl, is one of the six species endemic to the

island of Fogo. So far it was thought to be restricted to the semiarid zone in the southern and

western part of the island (Brochmann & al. 1997) but new distributional data give a somewhat

different picture. Two populations have been found in the subhumid zone at 1730 and I870 m,

one of several hundreds of individuals in the south-eastern part, the other of three individuals in

the north-western part. The latter stand with old and formerly impressive but now badly cut indi-

viduals is the first record of the species from the more humid northern half of the old crater rim.

Even though it is not assumable that the range of Echirom wclcanorunt exceeded considerably into

the northern part of the island. The factor limiting its distribution is, however, most likely not the

climate but the ~comorphology: where the rocky slopes replace the lapilli dominated slopes

Ec/rimn starts to diminish and becomes replaced by Etr/d~ntf~ic: rtrrPr,nrrr~. Arrenrisict ,qorqt,r,rt,~,,

Peri/doca koei~igdlcr subsp. chewlieri and other species (Leyens in prep). As (hc NNW par1 of 1he

old crater rim (Bordeira) is dominated by rocky slopes it seems probable that Echico,r in ihat part

has always been :I rare component of the vegetation.

Its conservation status should be maintained as Endangered (EN) because human pressure for

wood and animal fodder is quite severe. As animals prefer the soft flowering branches, the species

is preferably c~llccted in early flowering state and the achicvemen1 of scud maturi1y is I’rcYucmly

prcvcnled. thus rcprucr:rlion Itwough sccttlinps is very poor (ohs. T. Lcycns).

This inconspicuous. white-flowering endemic shrublet is known from the islands of Sto. Antlo,

S. Nicolau. Santiago. Fogo and Brava (Games & al. 1995b). Due to the lack ofsufficient data, i1s

general COUServltkw status was classified as Indeterminate (I) (Games & al. 1996).

Gn Fogo too it was qualified as indeterminate as already by Chevalier (1935) only one record

is mentioned from Fog0 (Espia pits de Mosteiros. I(HJ0 III. Chertrtier JS1.92) ;111d ;IISO (1~ Borgen

work by T. Leyens all around the higher elevations of Fogo the species was encountered only fou)

times (see below). All populations consisted of few or even one individual only. It was found in

the semiarid zone as well as in the subhutnid zones. As it is a very palatable species for all kind 01

livestock it can be taken for sure that its population sizes and distribution range has diminished

greatly. It is therefore classified as Critically Endangered (CR) for Fogo.

This endemic perennial herb is known from the islauds of Sto. AnlBo, S. Viccutc. Sta. I.u/ia. S.

Nicolau, Boavista, Maio, Santiago and Fogo (Brochmann & al. lY97) aud is here recorded for lhc

first time from the Ilheus do Rontbo (Le,vcrrs CV-YI-OS/). The species has a very wide ccologic;)l

antpli1ude, occurring from sea level to the highest elevations and in all moues of humidity cwct~l

the extrentely arid zone. Even though it is generally classified as Lower Risk (LR) its shr~ux (rn

Maio is considered Endangered (EN) (Games & al. 1996).

For Boavisla we sugges1 IO upgrade i1s sta1us IO Critically Endntlgered (CR) due IO the I’;ICI

that although it is lis1ed for this island (Hansen & Sunding 1985, Brochman & al lYY7) i1 has n(*l

been recorded by Diniz & Matos (1988) nor collected during the intensive field work in 10021~J-J.

Boavista is also one of the islands with severe pressure by overgrazing.

On Fogo, Brochmann & al. (1997) mention it as “absent in the lowlands”. App;~rcn1Iy 111c!

have overseen that Diniz & Ma~os (1987) give the species as a typical element of lhe arid li11ot;tl

communities in the south-eastern part of the island (e.g. Ponta da Praia GrandcJ. in 111~

north-western Dart of the island (Ponta da Salina) and probably also in the north-cax1cru part III

the island (Fajazinha, Ponta Queimada).

The presence of 1he species is confirmed for Sla. Luzia where it WBS collcc~cd in I’J’Jh. 1)) I’III

was collfirmed by local fishermen. there have been no goats on 1he island in the last yc;Jrs. ‘l‘l111\

of s011)e hundreds of individuals was discovered nearby, coveriug an area of approxima(ely 1.5

of FU~TIIW~I Jiwritkt sntl hr/ctr~cf wntora. This largest known population is strongly threatened

by exlensivc goal and donkey grazing as was proven by (he findings of fresh excrements. Urgent

measures are ncccssary lo avoid Ihc deslruciion of this probably last remnant of a scrub of this

kind on the archipelago. AS this only known larger population has a very limited distribution (he

This very variahlr subshrub is known on the Cape Verde islands from Boavista. Maio and Santi-

ago, and grows iI1 a rather wide range of habitats. The plants may hang from steep cliffs. climb jn

trees. or creep oo the ground in dry stony planes and on sand dunes (see also Duarte 1995). Vege-

talion analysis show lhal the species was probably a characteristic element ofdricr planes.

ln 1995 W. L&in found lhis sprcies also WI the island of Sal. in similar conditions. Only few

plants were obssrvcd in the vicinity of (he village of Espargos. Pe()di()S fur(herda(a i( is classified
