Recolonization and mass propagation of Banspata (Podocarpus neriifolius)
Implementing Entity : Institute of Forestry and Environmental Sciences, Chittagong University
Location : Institute of Forestry and Environmental Sciences, Chittagong University (IFESCU), Chittagong
Duration : 5 Years (November 2006 to October 2011)
Budget : BDT. 3,000,000 (USD 1.00 = BDT 69.00 approx.)
Context : This is the only conifer (soft wood) species growing naturally in the forests of Cox's Bazar (Ukhia) and Chittagong Hill Tracts (Publakhali). Due to clear felling of the forests this species has become endangered. This natural conifer species will be extinct very soon unless an appropriate rescue measure is taken. As a soft wood species it has a great demand in pencil, package and pulp industries.
Objectives :
  1. Conservation of this conifer species from the threat of extinction.
  2. Focus on its industrial values.
  3. Enhance scenic beauty and enrich the ecosystem of the country.
Main Activities :
  1. Stocktaking of the current status of Banspata in Bangladesh.
  2. Collection of Banspata germplasm from forests for selection and multiplication
  3. Mass propagation of selected germplasm of Banspata through seedling raising & vegetative method.
  4. Development of tissue culture protocol for Banspata.
  5. Pursue Forest Department and other relevant entities in public and private sectors for recolonization and restoration of habitat through plantation of Banspata.
  6. Awareness raising of stakeholders for the conservation, recolonization and propagation of Banspata
  7. Preparation and publication of a nursery manual for Banspata.
  8. Perform activities regarding to sales, distribution and dissemination of products produced by the Grantee / research organization / academic institution and/or local community as the case may be.
  9. Dissemination of propagation techniques of Banspata to relevant stakeholders through training and workshops.
  10. Identify location(s) to establish Banspata plantation for habitat restoration.
  11. Establishment of seed orchard of Banspata.
Progress/Achievements (as of March 2010) :
  1. Exploration made in the natural ranges and plantations in south eastern hills (Chittagong Hill Tracts) and north eastern parts (Sylhet) of Bangladesh and identified a few trees in the natural forests of Cox's Bazar (Ukhiya, Teknaf, Dulhazara), Chittagong (Hazarikhil, Hyako, Korerhat, Sitakunda), Khagrachari, Rangamati and Sylhet (Lawachara, Rema Kalenga). There is no mother trees (PPT of seed orchard) found in the exploration area. Natural regeneration was found specially in a plantation stand of Lawachara. Seeds and propagules were collected from these trees and seedlings and were raised in the IFESCU nursery. Identified individuals earmarked for collection of seeds and cuttings in future.
  2. A permanent propagator house (4.8 m x 14 m) was constructed and few propagules (twigs, juvenile branch/shoot cuttings of Banspata) were set for rooting trials. Few experiments were set to find the effect of hormones (IBA, Rhizobex) on rooting trials of Banspata propagules/cuttings in the propagator.
  3. Using a simple propagator house, IFESCU has been able to achieve 30 - 40 % success rate in propagating the species through stem cuttings. It has established two hedge bed and a clonal orchard of Banspata at IFESCU campus and have started to collect juvenile shoots for preparing shoot cuttings for rooting. It has produced 5000 rooted seedlings from the shoot cuttings and 409 seedlings from the seeds; and have planted 100 seedlings (50 from seed sources and 50 from shoot cutting sources). It distributed 210 propagules through Forest Department and NGOs (National Botanical Garden, Rangamati Forest Division, Bangabandhu Safary Park, Cox's Bazar Forest Divisions, CODEC, PHP, BIRAM, Chitttagong Forest Division and Sitakunda Eco-Park) for planting.
  4. Established a hedge bed of 30 Banspata seedlings in the IFESCU nursery. 23 seedlings are in the poly bags which will be planted later and some 1000 cuttings are under process for rooting in the propagator. Another 500 seeds of Banspata had been sown in the propagator house at the end of December 2007.
  5. Location data (longitude, latitude and elevation) was recorded to develop distribution map of Banspata using hand held GPS machine.
