Presentation Transcript

Slide1:

“Biodiversity restoration in UAE .” Mikhail Korshunov Al- Mayya group, United Arab Emirates

Slide2:

Biodiversity restoration in UAE.

Slide3:

We proceeded with the works by theme “Biodiversity conservation in UAE”. We connect with specialists from outside offices into frame of this project.

Slide4:

We together with botanic specialists carried out common expedition in Wadi Tarabat . We accounted 123 of the shrubs Acridocarpus orientalis Juss . We identified of Jebel Hafeet reptiles together with herpetologist from Sharjah B. C. Specialists from project “Fauna of UAE” help us with identify of insect species. Svetlana Ashbi , ornithologist from UK, helped us with identify of birds from Jebel Hafeet

Slide5:

The works by theme “Biodiversity conservation in UAE”. Within the limits of the Program of preservation of a biodiversity of mountains experiments on artificial of the maintenance and cultivation of various representatives of fauna are made: - We have grown up butterflies Giant Skipper ( Coeliades anchiises jucunda ) and Oleander hawk ( Deilephilia nerii ) from eggs and have set free. Now we have an experience on artificial of the cultivation and maintenance of separate species of butterflies from the nature. - We develop technology of the maintenance and cultivation of hedgehogs. From 4 parents 20 young individuals are received, from them 5 individuals are already set free. - Experiment under the maintenance of 3 species rodents proceeds. Oleander Hawks Giant Skipper Hedgehog

Slide6:

Cycle of Giant Skipper ( Coeliades anchiises jucunda ) development

Slide7:

Cycle of Oleander hawk ( Deilephilia nerii ) development

Slide8:

Stages of Brandt’s H edgehog ( Paraechinus hypomelas ) development

Slide9:

- The sex-age structure of the tahr group in the territory of Jebel Hafeet consists of males – 41% (74 met animals) in the reborn population, females – 35% (63) and youngsters – 24% (42) with the relation of genders 1: 0.85, i.e. ♂ - 54%, ♀ - 46%. One female relates to 0.67 of kid. - The sex ratio of population Arabian Tahr according to supervision for 24 years (1977-2001) was always close 1 : 1 in Oman. The quantity of young growth on one female was 0,41 (±0,221) and varied between 0,069 and 0,650 (Robinson, 2004). - In the Jebel Hafeet nursery since 2003 till 2012, the relation of new born males 151 (53.7%) to females 130 (46.3%) amounted to 1: 0.87.

Slide10:

Rut of Arabian Tahr. Elements and phases of reproductive behaviour . 1. BEGINNING OF RUT 2. POSE LOW-STRETCH . 3. INSPECTION . 4. FLEMMING .

Slide11:

5.FRONT-KICK. 6. FREEZING BEHAVIOUR . 7. RUSH . 8. APPEAL . 9. SPRAYING. This phase characterized by increase of activity and marking territories by Arabian Tahr males.

Slide12:

10 . MOUNTING 11 . REFUSAL OF YOUNG FEMALE . Response of female on marking territories by male. Realization of male hyperactivity – masturbation.

Slide13:

Rare rains cannot provide plentiful herbage. Presence and availability of natural water sources, scarcity of the vegetation, which efficiency on the average does not exceed 1,39 ts /hectares a year, and mosaic a vegetative cover substantially influence distribution of Arabian T ahrs on territory that first of all affects features of reproductive strategy of Arabian tahrs.

Because of organizing water points at the mountain, we rich achieve to increase available food for arabian tahr, especially fresh green. Ephemeras are appeared. :

Slide15:

Result : Amount of Arabian tahr at Jabel Hafeet in 7 years increase from 4 to 30-51 animals, what clearly shows efficiency compliance of nature conservation standards. Satisfice of minimum, but important ecological and physiological animals needs, we can conserve this species, and increase its numbers with all population parameters restoration, even at strongest anthropogenic pressure. Years 2005 2006 2007 2008 2009 2010 2011 2012 Frequency                 Quantity of Tahrs for day of supervision 0.34 0.21 0.53 0.62 0.86 1.5 2.23 2.54 Relative occurrence on days   0.17 0.21 0.26 0.31 0.43 1.0 0.85 0.73

Slide16:

Release of arabian tahrs in natural habitat in Wadi Wurrayah national park (Fujairah, UAE)

Slide17:

Female of arabian tahr at natural habitat. Male of arabian tahr at natural habitat.

Slide18:

Measurements of the grows dynamics of Acacia tortilis sprouts in nursery. At future this sprouts will be planted at Arabian tahr enclosures and its natural habitat.

Slide19:

Views to the future – multi-species and ecosystem approach to conservation and restoration of biodiversity.

Slide20:

Thank you for attention! We thanks H.H. Sheikh Mohamed bin Hamad Mohamed for his help.
