The Giraffe Conservation Foundation (GCF) is dedicated to a sustainable future for all giraffe populations in the wild. Country Profile United Republic of Tanzania Giraffe Conservation Status Report Sub-region: East Africa General statistics Size of country: 947,303 km² Size of protected areas / percentage protected area coverage: 38% Species and subspecies Until recently, it was widely recognised that there was only one species and nine subspecies of giraffe. New genetic research, conducted by the Giraffe Conservation Foundation (GCF) and partners, has shown that there are in fact four distinct species and five subspecies of giraffe. These ground-breaking findings will enhance future giraffe research, conservation and management. To confirm these findings, further research is currently carried out by GCF and partners to correlate current and new genetics findings with the traditional classification taxonomy methods, based on morphology and geography. Based on these findings the new taxonomy has been used in the Country Profile and the following giraffe species and subspecies occur in Tanzania (Fennessy et al. 2016): Masai giraffe – Giraffa tippelskirchi (formerly Giraffa camelopardalis tippelskirchi) Local name: Twiga (Kiswahili) Conservation Status IUCN Red List (IUCN 2016) The IUCN currently recognises one species and nine subspecies of giraffe (see above).

there is nodirectmentionof giraffe as Tanzania’s national animal in the constitution, giraffe havebeen

prominently used in Tanzanian symbolism. For instance, giraffewere used aswatermarks on Tanzanian

banknotes issued since independence in 1961 to the 2011 series (Linzmayer 2011). In fact, the Bank of

Tanzania unveiled the ‘Giraffe banknote series’ in 1997 whereby the 500, 1,000, 5,000, and 10,000

Issues/threats

TanzaniaishometotheMasaigiraffeonly,distributedthroughoutnorthernandcentralareasofthecountry.

Themost important contemporary threats to theMasai giraffe are illegal hunting, land use change and

disease.

Masaigiraffeareillegallyhuntedusingguns,snaresanddogsformeat,aswellasforproductssuchashide,

bonesandtailhairs(Caro2008;Straussetal.2015).InSerengetiNationalPark(NP),adultgiraffeareillegally

largequantityofmeat,itisnotclearthatgiraffearepreferredasasourceofbushmeat(e.g.Straussetal.

2015).Giraffeproductsarealso recorded in traditionalmedicine in someareasofTanzania, inparticular

giraffe bone marrow and brains are believed to cure HIV/AIDS (Arusha Times 2004; Nkwame 2007).

Additionally,tail-hairandotherproductsareusedtomakebraceletsandtrinketsfortourists(Mbogoni2013).

the Serengeti population. Poaching ofMasai giraffe appears to be alsowidespread in the Katavi-Rukwa

ecosystem (Caro2008)and theWestKilimanjarocorridor (Nkwame2007). Illegalhuntinghaspotentially

Extensive land use change has occurred across some parts of the Masai giraffe range. The majority of

Tanzania’shumanpopulationrelyonsubsistencefarming,yetincreasinghumanpopulationsareleadingto

expansionandappearanceofsettlements,isincreasing(Soini2005).Whilemanagementareas(inhabitedby

both livestock andwildlife) showno reduction in species richness, they do show a difference in species

composition(Kiffneretal.2015).Thismightbeaspecialcasehowever,asareaswithlivestockinTanzania

havesmallerwildlifenumbers.Importantly,thecoexistenceoflivestockandwildlifeisfundamentaltothe

continued survival ofmany largemammal species in Tanzania (and other areas of Africa).While such a

situation may increase the likelihood of broader human-wildlife conflict, the impact on giraffe is likely

minimalasdiseasetransmission,competitionforresourcesandillegalhuntingmaybemoreseriousthreats

(Kiffneretal.2015).

Increasingly,giraffeskindisease(GSD),aninfectioncharacterisedbygreyish-brownlesionsthatappearon

the forelimbsandneckof adult and sub-adult giraffe (Fig. 2), appears tobean indirect threat to giraffe

survivalinTanzania(Epaphrasetal.2012,Karimuriboetal.2011).WhileGSDwasfirstobservedinRuahaNP

GiraffewerecommonlyseeninmanyareasincludingtheSerengetiPlains,NgorongoroConservationArea,

Aroundthemiddleofthelastcentury,giraffeherdsnumbering30-40individualswereregularlyseeninthe

Studies conducted throughout the1960sand1970s in various locationsaround the countryoften found

density data was used to extrapolate to other areas in the park with a similar habitat. Based on this

extrapolationtheysuggestthetotalSerengetiNPpopulationwasapproximately3,500in2008-2010.Recent

SRF data from Serengeti NP estimated 5,886 ±1,221 giraffe for the same period (TAWIRI 2010). These

populationestimates,whencomparedtothoseofPellew(1983)in1975-76,suggestadeclineof67-86%.

However, SRFdata from the larger Serengeti ecosystem,which includes theMaswaGameReserve (GR),

Ikorongo GR, Grumeti GR, Ikona Wildlife Management Area (WMA), Makao WMA and Loliondo Game

Controlled Area (GCA) indicate a population of approximately 12,000 giraffe (TAWIRI 2010). The major

reasons forgiraffedeclines in theSerengetiecosystemare illegalhuntingandsnaring (HoareandBrown

2010;KilewoandMpanduji2010;Marealleetal.2010),disease(Bondetal.2016;Munezaetal.2016)and

food limitation causedby the increase in relative abundanceofunpalatable tree species, notablyAcacia

robusta.Other threatsnoted in theSerengeti ecosystem includeencroachment (in thewest, there isno
