Stephen Ellio, FORRU-­‐CMU Biology Department Faculty of Science Chiang Mai University Two stages of species selecLon: 1.  Which species to test? – “candidate” framework species. 2.  Using test results to decide which species to plant – “actual” framework species. Then start to collect original scienLfic informaLon from trials. Nursery trials 1.  GerminaLon and dormancy 2.  Seedling growth rates Field trials 1.  Survival and growth 2.  Shading out weeds 3.  AWracLveness to seed dispersers 4.  Economic producLvity Then … 1.  Collect data into a database 2.  Screen out species with unacceptably low survival rates in trials plots 3.  Then apply “Rank scores” … to select species for subsequent planLng. Rank Scores Want more details? Read Chapter 8 AdapLve Management 14 months old Melia toosendan (Meliaceae) End of 2nd growth season:-­‐ Survival: 98% Height: 705 cm Crown: 235 cm Bird perch tree. Prunus cerasoides D.Don (Rosaceae) End of 2nd growth season:-­‐ Survival: 88% Height: 303 cm Crown: 241 cm Fruits within 3 y. Erythrina subumbrans (Hassk.) Merr. (Papilionoideae) 18 months old, survived fire End 2nd growth season: Survival: 89% Height: 281 cm Crown: 280 cm Fire resilient, flowers have nectar What to do next? •  Who will do what? – plan the sharing of responsibiliLes, with staff/students. Get approval from your bosses. Mobilize your faculty/
oragnizaLon. •  IdenLfy nursery site and target forest site; survey laWer for species. •  Label pheno trees, idenLfy species (collect voucher specimens). Start pheno data collecLon and seed collecLon. •  Nursery construcLon(?) – nursery staff training. •  IdenLfy the planLng site -­‐ draj planLng plan – to plan seed collecLon.
