Now the grass is no longer cleared out of the grassland, as tractors need no litter or fodder; and the forest is untrimmed, now that rice is boiled on bottled gas cookers. So the areas of grassland and forest become darker and darker, impeding the growth of lilies and reducing their populations. Some lily populations have been reduced by plant collecting: L. japonicum 13
var. abeanum is a case in point, or perhaps L. japonicum Hyuga form. Other lily communities have certainly been destroyed by developments such as dam construction, road building and estate development. However, it must have been often the case that habitats are dying through environmental changes such as those which result from failure to trim grassland and forestry in the old ways. It can be said that L. auratum, L. callosum, L. japonicum and L. rubellum are the species whose existence in Japan has been influenced most by human lives. The Okinawa population of Lilium callosum (a population known from its yellow flowers as var. flaviflorum) was rediscovered for the first time in these 20 years. Yet it has already fallen victim to changing times, with changes in its habitat management. The island is in “Typhoon alley”, and the thatch which has been traditional for roofing material there has now given way to concrete. So grassland has been neglected, allowing over-abundant growth of Japanese silver grass over two metres in height, destroying almost all the lily’s habitats. On a visit last year we found just one population of 50 plants, where Imperata cylindrica grassland had been artificially weakened. As far as I know there is only one other population on the island now. Lilium nobilissimum was endemic to Kuchinoshima island, Kagoshima Prefecture, where its habitat was restricted to the ocean cliff. Lilium nobilissimum’s Japanese name is Tamoto-yuri: Tamoto is the pouch-forming sleeve of Japanese clothing, and in the past men lowered on a bamboo contraption slung from the cliff-top to gathered the bulbs of the lily kept them in this pouch. This precarious undertaking seems to have been all too successful: the lily is said to be extinct in the wild now. A few cultivated plants preserve the species. However, in our Yurigahara Park collection this lily’s germination rate has now declined to about 20%, which I think must be caused by inbreeding depression. Although we will outbreed the strain with another strain next summer, I am not very hopeful for the future, over the next several generations. [Editor’s note: This lily is also in cultivation in the UK, and perhaps elsewhere, but from seed kindly donated to the <strong>Lily</strong> <strong>Group</strong> distribution by Mr Arakawa in the past, so these plants are unlikely to help with the inbreeding problem.] Lilium alexandrae ranges over three islands of this same southern chain. Though it has been reduced by collection, it is sustained in the wild by the islander’s keen conservation work. The only surviving habitats of L. concolor are now confined to Shikoku Island, and the wild population declines. Lilium longiflorum, L. leichtlinii var. maximowiczii, L. speciosum, L. maculatum and L. medeoloides are common lilies in their original habitats, through exemplary preservation and conservation – a textbook case. 14
