Observations

Vladimir Dinets (e-mail, 2004.1.14) reports that Kalam, in Pakistan's Swat Valley, has a large forest of Cedrus deodara with some Picea smithiana and Pinus wallichiana. He also found it growing along the trail to Nanga Parbat Base Camp. "The trailhead is accessible from Gilgit by a hired jeep, or from Raikot Bridge on the Karakoram Highway by hitchhiking (early morning only). Near the trailhead are some Pinus gerardiana, Juniperus semiglobosa and Cupressus torulosa, higher up - Pinus wallichiana and Picea smithiana (slim, but up to 50 m tall)." See Dinets (2004) for further detail.
