I. EXECUTIVE SUMMARY

The Cerro de Hula Wind Park, legally known as Honduras 2000 Wind Project (“the Project”), hasbeen developed and is operated by the company Energía Eólica de Honduras S.A. (EEHSA),which is a member of the Globeleq Mesoamerica Energy Group. The Project is located in themunicipalities of Santa Ana and San Buenaventura in the Province of Francisco Morazan, about20 kilometers south of Tegucigalpa, Honduras. It takes up an area of 14 kilometers in Cerro deHula and Montaña de Izopo.

A Forest Assessment Study (“the Study”) was carried out in the area proposed to build five (05)aerogenerators and the main access to the project expansion (“the Expansion”) in thecommunity of El Tablon, Municipality of San Buenaventura, Province of Francisco Morazan, bythe company Energía Eólica de Honduras S.A. (EEHSA).

This Study allowed knowing the forest coverage existing in the proposed construction area. Inaddition to getting to know the existing forest resource, an inventory of 100% of the trees wasprepared by measuring all trees with a Diameter at Breast Height (DBH) equal to or above 10cm and counting all tress with a DBH below 10 cm.

Results show that there are 949 trees with a DBH equal to or higher than 10 cm distributed in 23species with a volume of 178,158392 m3 and 699 trees with a DBH under 10 cm distributed in16 species in the assessed area. The 5 most common species detected by the study areQuercus purulhana, Quercus segoviensis, Pinus tecunumanii, Quercus sapotifolia, and Pinuspseudostrobus. According to the CITES Appendices, none of the top 5 species in the inventoryare threatened or endangered.

Compliance with the compensatory measures should consider as much as possible plantinglocal species at specific sites identified together with the municipalities which are of interest tolocal groups.

II. BACKGROUND

EEHSA started the Project’s commercial operation on December 21, 2011, 24 km south ofTegucigalpa in the municipalities of San Buenaventura and Santa Ana in the Province ofFrancisco Morazan. The Project comprises 51 Gamesa G87 aerogenerators, each with acapacity of 2.0 MW, for a total installed power of 102 MW.

The Project construction would affect the forest cover in the area, so a series of studies werecarried out. The Escuela Nacional de Ciencias Forestales (ESNACIFOR) prepared in 2009 thefirst 100% forest inventory in the 13 construction areas; it determined the number of trees thatwould have to be cut to build the civil and electrical works and calculated the compensatorymeasures required by the Secretaría de Recursos Naturales y Ambiente (SERNA) [Ministry ofNatural Resources and Environment].

Currently, EEHSA is developing a project to expand the generation capacity of the Project byinstalling twelve (12) new aerogenerators distributed in four construction areas, of which threehad already been included in the study prepared by the ESNACIFOR. In fact, two of thosealready have aerogenerators installed in them.

This new forest inventory was developed in the community of El Tablon, municipality of SanBuenaventura, which is the place not considered in the original investigation carried out by theESNACIFOR. It covers an area of 4.619 hectares, which include a 30m-wide stretch to designand build the access road plus five platforms to build the foundations of the aerogenerators andmount the equipment.

III. OBJECTIVES

GENERAL OBJECTIVE

To carry out the forest assessment study for the Project expansion.

SPECIFIC OBJECTIVES

To identify the existing plant diversity in the various strata, including seedlings andsaplings.

To determine the dasometric characteristics of the species in the site. To certify whether or not the plant composition includes threatened or endangered

species according to the CITES Appendixes.

IV. LOCATION

The land called “El Tablon” is located in the Aldea San Isidro de Izopo, San Buenaventura,Province of Francisco Morazan, 24 kilometers south from the city of Tegucigalpa, according tomap sheet No. 1636. This land is part of the concession area granted by SERNA to EEHSA asper Legislative Decree No. 151-2008, published in La Gaceta No. 31.768 on November 22,2008.

IV.1 General Description

The land where part of this part of the expansion will be built is designated as area 14 (“theArea”), according to the internal coding system used by EEHSA. It has an area of 4.62 hectares(ha) distributed geometrically as follows: 30 m wide and 1.55 km long with five rectanglesbordering the 60 x 40 m access.

a) Topography:

The topography of Area 14 is regular with slopes ranging between a minimum of 5% and amaximum of 25%, which facilitates the constructions activities by reducing the number of cutsand fills.

b) Forest:

The forest cover in this part of the wind park expansion area is a mixed forest composed mostlyof pine and oak trees. The most common species identified at the site are the following: pine(Pinus tecunumanii), white pine (Pinus pseudostrobus), mountain oak (Quercus purulhana),yellow oak (Quercus segoviensis), holm or live oak (Quercus sapotifolia), avocado (Perseaamericana), guava (Psidium guajaba), Guachipilín (Diphysa americana).

V. MANPOWER

Unskilled labor used in this study was composed by people from the community. A crew of fourpeople participated in the study, including a forest engineer and three people who were trainedon how to gather information for the inventory.

VI. COMMENT

To prepare a forest assessment inventory, it is really important to have previously trainedpersonnel to collect the information in the field. Identifying species in the intervention area wherethe project expansion will be carried out is vital in order not to remove species that are eitherthreatened or endangered according to CITES Appendixes.

VII. METHODOLOGY

The Study consisted in preparing a 100% inventory by measuring all trees with a Diameter atBreast Height (DBH) equal to or above 10 cm and counting all tress with a DBH below 10 cm.

The intervention area where five aerogenerators will be installed comprises a stretch of 30 mwide and 1.55 km long, where the access will be built and five 40x60 cm rectangles around it tobuild the mounting platforms and foundations.

The dasometric variables measured for each tree included the DBH, total tree height (HT),commercial height (HC). In addition, tree species were identified and numbered and theircoordinates taken. Finally, a blue mark was painted at the tree base.

The heights of the dominant species were measured every five tree, while all trees of minorspecies were measured individually.

After the field work, all data were tallied using an Excel spreadsheet, where trees where dividedby species and diameter class in order to obtain the volume per diameter class and per species.

Logarithmic height regression was used for all other trees by tallying the date in Excel.

The equation used to obtain the volume per species was calculated using the Sistema deInventario de Bosque Privado y Público (SIBP2) [Private and Public Forest Inventory System]software.

To learn if the species in the 100% inventory were threatened or endangered, they wereidentified and compared against the CITES Appendixes.

To obtain the tree volumes, the most appropriate equations for the type of forest (Table 1) wereapplied to the inventory data.

VIII. MITIGATION MEASURES

a) Activities near protection stretches and bodies of water, if any, must be forbidden.b) Toxic elements, such as oil derivatives, machinery parts and accessories, must not be

dumped into bodies of water.c) Damages to vegetation outside the access path should be prevented or minimized.

X. CONCLUSIONS

The species representing the largest number of trees in the area inventories were the Quercuspurulhana, Quercus segoviensis, Quercus sapotifolia, Pinus tecunumanii, and Myrsine sp.

A total of 949 trees with a DBH equal to or higher than 10 cm and 699 trees with a DBH of less than10 cm were found in the area covered by the inventory; this information is the one that should beused as a reference to comply with the reforestation commitment.

The tree species found in the intervention area have not been reported as either threatened orendangered nor are they registered in the CITES Appendixes.

XI. RECOMMENDATIONS

1. The number of trees found and considered to calculate the volume in the inventoried areaincludes 949 trees with a DBH equal to or higher than 10 cm. Therefore, it is suggested toadjust the designs as much as possible to reduce this impact.

2. Compliance with the compensatory measures should considered as much as possibleplanting trees of local species and of interest to the area’s inhabitants at the sites identifiedin coordination with the municipalities.

3. Before starting the removal of trees or [other] activities in the Area, always work incoordination with the members of the Unidad Municipal Ambiental (UMA) [EnvironmentalMunicipality Unit] or those responsible of the ICF [Instituto de Conservación Forestal /Forest Conservation Institute] for the area to obtain any permits.
