Mauritius is reputed to have been the abode of some of rarest species of birds, reptiles and plants. Several of these
species, including the Dodo, became extinct as a result of rapid colonization, indiscriminate destruction of forest and
predation on wildlife. Globally, there is an urgency to preserve and conserve our biological diversity as we form
part of it, and further degradation may cause irreversible changes and damage.
The Vallée d’Osterlog Endemic Garden Foundation was established in 2007 and the Garden forms part of the
remnant native forests in the south-eastern part of Mauritius. It extends over 275ha of mountains and valleys,
contains pristine areas covered with adult specimens of rare endemic and indigenous flora, and is home to endemic
fauna some of which have been described in this booklet.
One of the statutory objectives of the Foundation, in line with the United Nations Convention on Biological Diversity, is the restoration and conservation of all threatened native biodiversity. Besides conservation and preservation
of the local genetic resources, the Foundation aims at developing the Vallée d’Osterlog into an attractive endemic
garden for the benefit of nature lovers, scientists and the public in general.
Surveys are being conducted for inventory and evaluation of native species within the Garden boundaries, as well

as identification of Invasive Alien Species which are causing degradation to the ecosystem. This booklet contains an
interim fauna inventory conducted in early 2010: five birds, two geckos, three mammals, one butterfly and several
molluscs found on the Mauritius list of protected species have been located. Unfortunately, the presence of exotic
animals such as tenrec, rats, monkeys, wild boars also compete with native fauna and endanger the survival of
these native species in the Garden.
It is hoped that the illustrations in this booklet will help readers identify these animals and insects, and encourage
them to support the ongoing efforts in biological diversity conservation. We are confident that a complete inventory
of the whole area may reveal the presence of other rare endemic species. Reintroduction of endemic species that once
inhabited the Vallée D’Osterlog Garden area is also envisaged.
The Foundation is working towards the opening of the Garden to the public, for visitors to discover and admire the
rich biodiversity Mother Earth has given to us.
We wish to express our sincere and heartfelt thanks to all those who have contributed to the publication of this
booklet

Preface
It is with great pleasure that I associate myself once again with the Vallée
D’Osterlog Endemic Garden Foundation on the occasion of its publication on an
interim inventory of fauna within Vallée D’Osterlog.
Since the setting up of the Vallée D’Osterlog Endemic Garden Foundation in 2007, the Board and the
staff of the Foundation have always made it a point to mark the International Day for Biological
Diversity through the publication of interim inventories on the endemic species which exist within the
275 ha of land in the Vallée. Whilst the first two publications were exclusively focused on the native
flora inventories within the garden, this third publication contains a list of fauna that have been identified up to now within the boundaries of the Vallée.
This present publication is in line with the theme to mark the International Year of Forests as declared
by the United Nations for Year 2011 and the theme for this year’s celebration is Forest Biodiversity.
It is an undisputed fact that our overall well being depends on our biodiversity and a quite high percentage of our global economy is based on biological products and processess. However, forest biodiversity is increasingly threatened as a result of deforestation, fragmentation, climate change and other
stressors. This Foundation is fully committed to protect the biological resources with an aim of having
a sustainable forest.
In Mauritius, I am glad to say that much effort is being geared towards the promotion of the conservation and the sustainable use of our biological diversity. The setting up of the Vallée D’Osterlog Endemic Garden Foundation which has as main objective to care for, conserve and preserve the endemic
flora and fauna in the garden is one such example. Moreover, this project is also in line with Government’s vision to sustain a Green Mauritius and mitigate the impact of climate change. Once funds are
secured by the Foundation, the Master plan for the development of the garden will be implemented.
This publication has highlighted an array of endemic fauna species within the garden and will be a
useful tool for raising awareness among the public on the variety of endemic fauna species that exist
therein. In addition, it will be a valuable reference for scientists, researchers and students on endemic
fauna located within the garden. I am aware that it will take a lot of time to carry out a complete
inventory of all endemic flora and fauna species within the 275 ha of land, but with the commitment of
the staff of the Foundation and the members of the Sub-Committee on Fauna and Flora Inventory, I
am confident that this can be achieved.
I wish to convey my deepest and sincere appreciation to all the officers who have worked on this publication.

Since its creation, the Foundation has been commemorating the International
Day for Biological Diversity through a publication.

This year, it is an inventory, albeit interim, of the fauna within the Garden.
The Masterplan for the Garden having been approved by Government, the Foundation is now
seeking to raise the necessary funds for its implementation. In the meantime, work is ongoing to
identify the multitude of species, flora and fauna, within the garden, and to remove alien invasive
species by the team of employees who have been trained for this work.

The Foundation is committed to preservation and protection of endemic flora and fauna within
the Garden, and one of the means is through inventories that will have to be carried out at predetermined intervals, to collect data on how the endemic species are faring.

I wish to record my deep appreciation to the Chairperson and members of the Fauna Inventory
Sub-Committee who have devoted themselves for the timely realization of this year’s publication.
We have been providing these publications to educational institutions, and we hope that eventually, as our youth learn to recognize and identify the endemic species, they will give feedback to
the Foundation of what they have seen, where, and in what numbers. This will be their personal
and most valuable contribution in the protection of our endemic species.

As years passed, fauna alien species that become invasive are considered to be the main direct
driver of biological diversity loss throughout Mauritius.
Increasing travel, trade, and tourism associated with globalisation and expansion of the
human population have facilitated intentional and unintentional movement of species beyond
natural biogeographical barriers are becoming matters of interest in Invasive Alien Species
(IAS) at a particular location.
IAS may also alter the evolutionary pathway of native species by competitive exclusion,
niche displacement, hybridization, predation, and ultimately extinction. IAS themselves may
also evolve due to interactions with native species and with their new environment.
It is clear that IAS can produce substantial environmental and economic damage, and their
negative effects are exacerbated by climate change, pollution, habitat loss and humaninduced disturbance. Increasing domination by a few invasive species increases global homogenization of biodiversity, reducing local diversity and distinctiveness.
Fauna IAS prevent the regeneration of native plants,for instance monkeys (Macaca fascicu-
laris) often pick and bite immature fruits and flowers of native trees so preventing the seeds
from maturing and germinating. Sus scrofa – wild boar often gig up and eat any seedlings
that do manage to germinate. Mauritius rich native fauna have been impoverished due to
several reasons and one is predation from fauna IAS such as monkeys, rats (Rattus rattus,
Rattus norvegicus) and through competition by aggressive exotic birds like Indian Mynah
(Aeridotheres thristis), Red Whiskered Bulbul (Pycnonotus jacosus).

IAS can also directly affect human health through infectious diseases imported by travellers

or vectored by exotic species of birds, rodents and insects. IAS also have indirect health effects on humans as a result of the use of pesticides and herbicides for their control which infiltrate water and soil.
