TheWondiboy Peninsula, also known as theWondiwoi,Wandammen (spelled locallyWandamen),Wondama, or in old sourcesMandamy[2][3] is a mountainouspeninsula inWondama Bay Regency,Western New Guinea. It extends northwards from theBird's Neck Isthmus intoCenderawasih Bay, and is composed administratively of the Rasiei, Wondiboy, Wasior and Teluk Duairi Districts (kecamatan) within the regency. At the northern end of the peninsula the land breaks up into a series of islands which form Roon District, of which the largest is Roon Island.
Separate from theNew Guinea Highlands, the mountain chain is northwest of theKobowre Mountains summiting inDogiyai Regency. These densely-forested mountains run north and south along the spine of the peninsula, rising from the shore up to 2,250 metres elevation, and extending southwards into the Bird's Neck Isthmus.[4] The eastern slope of the mountains is steeper than the western slope, and constitutes a thin coastal strip along the east coast of the peninsula which actually forms Teluk Umar District withinNabire Regency ofCentral Papua Province.
Lowland rain forest covers the lower slopes of the range, withmontane rain forest at higher elevations. Lowland forests extend from sea level to approximately 1000 metres elevation. Lower montane forests are dominated byCastanopsis acuminatissima and species oflaurels. Southern beech (Nothofagus spp.) is predominant in uppermontane forests, and the trees are often covered inmosses and otherepiphytes.[5]
Most of the Peninsula is covered byPegunungan Wondiboy Nature Reserve, which covers an area of 795 km2 (307 sq mi).[1]
The nameWandamen orWondama comes from theAustronesianWamesa language wordWon meaning "people" andDama meaning "come", so combined the word means, "the place where people come". MeanwhileMandamy orMandama comes from theBiak language with the same meaning.[3]
