DESCRIPTION

This is an independent report regarding Greenwood Management and its operations in Brazil. This report was prepared prior to the establishment of some of the company's forestry investment in Brazil. Focusing on the establishment of eucalyptus farm forestry crops on land owned by Greenwood management in the state of Bahia, Brazil this report uses commercial forestry models projected expected growth and yields for the tree crops grown using site specific date including meteorological data, soil data, and current growth and yields being achieved in the region. Greenwood Management started the establishment of its first forestry investments in the region in 2009 with the acquisition of several key sites centered around its operating base in the region. The company has since grown to become one of the larger forest operators in the region and currently manages around 5,000 hectares of forestry land in the region. Greenwood Management will be expanding this area further over the coming years and is already in the planning stages of developing a further 3,000 hectares of barren land for the companies reforestation projects in the region.

Introduction and rationale

Th is te ch nical re port is an inde pe nde nt ass e s sm e nt of Eucalyptus plantation productivity bas e d on re m ote ly s e ns e d and acq uire d data for th e tw o prope rty s ite s , Faze nda Tropical and Faze nda Santa Maria, locate d close to Catolandia and Baianopolis Municipalitie s , Micro Re gion of Extre m o O e ste Baiano, in Re gion of Bah ia, Brazil. Th e product is bas e d on re m ote ly s e ns e d and m ode le d data, w ith no fie ld ass e s sm e nts , and it is to be us e d for an inde pe nde nt com parison of th e grow th proje ctions and fore st m anage m e nt plans re porte d by Gre e nw ood Manage m e nt.

Brie f note about th e Faze nda s ite s

Th e tw o s ite s e xam ine d, as also pre s e nte d in re le vant m aps, are locate d in an are a of Brazil w ith strong agricultural prim ary s e ctor productivity, close to th e are a of Barre iras , at th e re gion of Bah ia, Brazil. Th e approxim ate surface are as (as re porte d from Gre e nw ood Manage m e nt) are ~ 9 00 H e ctare s for Faze nda Tropical, and 205 h e ctare s approxim ate ly for

Faze nda Santa Maria. Ple as e note th at grow th proje ctions in th is docum e nt are re porte d on a pe r h e ctare bas is for ave rage productivity sce narios for th e tw o s ite s , so it is e asy w ith s im ple m ultiplication to e xam ine th e stand grow th for e ach are a plante d w ith Eucalyptus .

Soil Re source s

According to re vie w e d data source s th e soils of th e tw o s ite s are class ifie d as Latossolo Ve rm e lh o Am are lo D istrofico (IBGE, 25, 26, 27, 28). Such soil is re porte d in m any s ite s of Eucalyptus plantation grow th , as in scie ntific studie s re vie w e d (16, 17, 18, 19 and oth e rs). Bas e d on th is re vie w , th is is a m e dium to prom ine nt clay te xture soil, w ith low nutrie nt availability and low fe rtility le ve ls. H ow e ve r, according to lite rature re vie w , th e re are ce rtain s ite and soil am e ndm e nt m e th odologie s to im prove soil conditions for plant grow th , and it is re porte d th at a lot of agricultural production in Brazil is com ing from such soils. Spe cifically for Eucalyptus, th e re w e re re vie w e d num e rous studie s of plantations grow ing on e xactly th e sam e soil class e ith e r in th e Re gion of Bah ia and in th e ne igh boring Re gion of Minas Ge rais re porting good (16, 17, 18, 19 and oth e rs) and in ce rtain cas e s ve ry h igh grow th tre nds give n appropriate s ite tre atm e nts . Th e re fore , th e s e studie s w e re us e d to cross com pare and locally adapt our m ode ling re sults. To re pre s e nt th e cas e s w h e re soil fe rtility is low , or h igh e r due to s ite tre atm e nts , s e parate grow th s ite q uality cas e s are us e d.

As pre s e nte d in re le vant graph s and docum e nte d in th is re port, th e Clim atic W ate r Balance is de ficit for som e of th e dry m onth s of th e ye ar and th e grow ing pe riod of Eucalyptus, and th us artificial w ate r availability can re duce th e plant w ate r ne e ds and aid into plantation grow th . Irrigation is part of th e m anage m e nt re gim e of th e plantations according to Gre e nw ood Manage m e nt re ports , to cove r any available soil w ate r plant ne e ds , and so it is include d and m ode le d in th e grow th proje ctions of th is docum e nt.
