Detailed description of how to reach location and access road description: The seed source consists of several scattered groups of neem. The main part of the seed source is near the Oodahela Tea Estate. To reach this part follow the road from Chittagong 33 km towards the north to Nazir Hat. At the boarder of the city, you pass the Forhadabad High School on your left hand. Leave the paved road and turn to the left 10 meters after. Follow the road and 1.3 km after you will cross the railway, continue another 2 km and cross the small bridge to the factory of the Oodehela Tea Estate. 200 m from here along the road the corner of this part of the seed source is defined by the road and a path going to the right towards the village.
To reach the other part of the seed source you will have to follow the road from Chittagong towards the north to Nazir Hat, pass the Forhadabad High School on your left hand and follow the road another 2 km to the Forest Range Office appears on your left hand side. From here you can walk to the Nazir Hat Railway Station along the small path.
The area is accessible all year.
Natural boundaries: The limit of the seed source towards southeast is the access road. To the west the area ends at the planted forest. The railway delineates the seed source towards East and the source ends at the Nazir Hat Railway Station. From this point there is no natural boundary, however the seed source ends towards North at a line straight West from the Nazir Hat Railway Station.
The site is mainly flat land with paddy fields and home homesteads in between. The village within the main part of the seed source is located slightly higher at some small hills. The trees are found at all aspects.
The soil is brown clay loam with small spots of reddish soil. The soil structure is fine and the drainage is generally good, however, in some parts of the area, the trees are found near the ponds where the soil is more waterlogged and drainage is poor.
There is no nearby contaminating seed sources , i.e. no plantings with introduced material in the vicinity of the area.
Mean annual rainfall: Around 2800 mm with a drier season from September to April.
Mean annual temperature: 25,7ºC
Climate Station:Chittagong
Total area is approx. 400 ha. The stand is uneven aged with trees ranging from 0-60 years. Villagers say that neem has come by it self, and that it is not planted. Natural regeneration is present. Planted species in the area include banana, mango and Albizzia sp. Neem trees were found in homesteads and scattered throughout the area. A more dense area with an extension of 7 ha is located near the Oodahela Tea Estate.
The majority of the trees are healthy with a dominant or co-dominant crown development. The stemform is generally straight. Mean height of dominant trees varies between 7 and 12 m. Some trees outside the central part of the seed source are heavily pruned.
Villagers estimate that each tree yields around 7 kg every year. There is no use of neem seed in the tribal village. In the homesteads, neem is used for several purposes including toothbrushes, but the seed is not used. Seed collection will be permitted by the villagers.
Seed collection period is May-June.
Labour is easily available from the tribal village in the main part of the seed source.
It seems that the neem is not under pressure in the area. In addition, the forest guard lives next to the tribal village in the central part of the seed source.

Detailed description of how to reach location and access road description: Chapai Nawabganj is situated approx. 45 km northeast of Rajshahi. The road to Sibganj is followed through Chapai Nawabganj, just after the new bridge over the Mahananda river is crossed, the village of Barogharia is reached. The village comprises the provenance stand. Access is via a metalled road to the stand.
Natural boundaries: The village of Barogharia comprises the provenance stand in accordance with the sketch map. On the western and eastern side of the village there are mango orchards, on the southern side is the river.
The area consists of flat land approx. 8-10 m above the river.
The soil is grey clay of alluvial origin, with a very fine structure and medium to good drainage. Distance to ground water is approx. 10-12 m.
Annual rainfall:
mim. 923 mm
mean 1540 mm
max. 1919 mm
Mean annual temperature: 30 year data from Rajshahi 45 km to the southeast.
Dry season : 6 months of dry season from October to end of March.
Total area is approx. 21 ha. Age of the trees varies from 0 to 40 years. Apparently all trees are from natural regeneration. In parts of the stand there is abundent natural regeneration.
The trees were found in homesteads with 5-10 trees per homestead, probably up to 250 trees altogether within the stand.
The larger trees were 14-16 m high, with diameter at breast height from 35-45 cm. The trees were healthy, unpruned, and reasonably straight with an open crown. In the homesteads they were found together with mango, bamboo, jackfruit and guava.
On average each tree will produce an estimated 10kg of seed per year, which means that up to 2500 kg of seeds can be harvested annually. Seed collection period is mid-June to mid-July. There should be no problem in obtaining permission to collect seed from the homestead owners.
Labour is available from Chapai Nawabganj Forest Extension, Nursery and Training Centre.
Presently no need for conservation.
The seed source can be extended to nearby villages or to the town of Chapai Nawapganj if required.

Detailed description
of how to reach location and access road description:
Vientiane, the capital of Laos P.D.R,,is located within the provenance
seed stand.
Access road description: Most of the trees are found in villages situated along the main roads to Vientiane.
Natural boundaries: The Mekong river makes up the southern border, the northern border is located 80 km north of Vientiane on road No. 13, where the hills start. The eastern border is the province of Boli Kham Xai, located app. 50 km east of Vientiane on road No.13.
The area consists mainly of flat land used for paddy fields, interrupted by villages and uneven land used for grazing.
The soil is sandy loam, with good drainage. Distance to groundwater is approx. 4-8 m judged from deep wells in the area.
Rainfall: 1540 mm averaged over 38 year, data from Vientiane airport.
Dry season: 5 months of dry season from November to end of March.
Total area is approx. 3000 km2. Age of the trees varied from 0 to 40 years.
The trees are only found in villages with normally 2-5 trees per village, but because the locals eat the flowers, it is difficult to find trees with enough fruit, and therefore the normal rate of success is about 1 tree pr. 5 villages. One exception from this pattern was that in the old village of Moung Kout with 12 trees. It was told that at least a couple of the trees were left with flowers on, because the flowers had a bitter taste. The fact that the trees are only found in villages indicates that the provenance is outside its natural distribution. There was good natural regeneration, and empty skins under every tree showed that the fruits were eaten by fruitbats which increases the possibility of seed dispersal.
Apparantly all trees were from natural regeneration, several was probably dug up in one place and then transfered to another, for example when a new village was established. 5 of the trees are located in tempel grounds.
The larger trees have a height of up to 15 m high, with diameters reaching 40 cm. The trees were healthy, heavily pruned due to flower harvest, and reasonably straight with an open crown.
If trees are left unpruned they will yield betwen 5 kg and 15 kg of fruit which corresponds to 1-3 kg of clean seed (stones) per tree. Seed collection period is mid April to beginning of May. There should be no problem in obtaining permission to collect seed from the homestead owners.
Labour is available from Nam Souang Silvicultural Research Centre, and from the villages.
Mr. Doungphet Lattanasouk from Nam Souang Silvicultural Research Centre will contact the farmers who own the trees that were collected from in April 1995. He will ask if trees can be left for seed production, and he will put up signs on the trees with number and a request to leave them unpruned. Judged from the responses eceived when doing seed collection, there should be no problem in obtaining such an agreement with the farmers.
The provenance seed stand comprises the main floodplain in which Vientiane is located, the floodplain is bordered by hills and by the Mekong river. It is therefore not feasible to extend the provenance seed stand.

Natural boundaries: The area has distinct and easily defined boundaries. The area is not isolated from the natural neem around, but this is not important, because the origin is the surrounding populations.
The provenance comprises plantations of neem established from the year 1978 (2513) and onwards. The total area of neem by 1988 is around 600 ha.
The area is originally degenerated dry dipterocarp land with poor sandy podsolic soils. Most of the original forest has been cleared and replaced by plantations of various species, mainly neem.
Rainfall: mean: 1145 mm
A pronounced dry season during the months of November-March.
Nearest weather station is at Kanchanaburi.
Area of neem by 1988 is around 600 hectares. Seed for the plantations have been collected by Headman, Nai Somchai, around the village Ban Don Sa, and around Ban Huai Talung about 13 kilometers South-West of the plantation area.
The plantations are generally planted at 4 x 4 meter spacing, the survival is high, and they appear uniform, and the trees are as a whole of good form.
The total production of seed from the plantations may conservatively be set at 3000 kg per year, or enough for around 3000 hectares of plantations. Possible time of collection is March to April.
Labour is available in the nearby villages, or else the Central Research Center can provide seed collectors.
The area is under management and control of the Forest Protection Unit, Royal Forest Department Bangkok.
There is no need for conservation, but information should be obtained from the Protection Unit regarding the working plans for the plantations, including rotation age.
The area would normally produce sufficient quantity of seed. Else, the provenance may be extended toward south around Ban Don Sa.
