Species and Family Common Names Remarks
TREES
Quercus gulielmi-treleasei,
(Fagaceae)
White oak (roble encino, roble blanco) Oak, roble, Quercus costaricensis Montane (2300-3200m). This species and two other oaks, Q. copeyensis and Q. costaricensis, show high abundance and basal area (Jiménez et al. 1988; Orozco 1991; ANCON 1993; Koomen 1993). Source: Smithsonian  Quercus is the dominant species of the lower montane Talamanca cloud forest (Kappelle et al., Los Bosques de Roble (Quercus) de la Cordillera de Talamanca). The saplings are easy to find all over the area around Cloudbridge. Q. costaricensis listed as "vulnerable" by the IUCN . 500 Q. gulielmi-treleasei planted in 2002.
Quercus rapurahuensis
Q. seemannii, Q. oocarpa
(Fagaceae)

Oak (roble) quercus rapurahuensis: oak, roble Lower montane (1500-2300m): The oak Q. seemannii, sometimes as tall as 40 m, is frequent, whereas Q. oocarpa and Q. rapurahuensis are less common (Jiménez-Marín and Chaverri-Polini 1991). Source: Smithsonian . Q. rapurahuensis listed as "vulnerable" by the IUCN . Photo taken on the trail to Chirripo. 50 Q. rapurahuensis acorns planted in 2002.
Sapium pachystachys
(Euphorbiaceae)
Yos Sapium pachystachys: Yos Aug 02 Lower montane (1500-2300m) canopy species. Source: Smithsonian . One has been seen in the forest alongside the Upper Meadow of Cloudbridge. 100 planted in 2002.
Cornus disciflora
(Cornaceae)
Lloró Cornus disciflora Lloro Aug 02 Lower montane (1500-2300m) canopy species. Source: Smithsonian  Listed as "vulnerable" by the IUCN.  Lloro is one of the finest woods in Costa Rica. A rich dark chocolate color, extremely hard and durable. Lloro seeds are hard to germinate as their shell is tough. One must submerge the seed in boiling water for a minute before germinating to soften the outer surface. Their germination rate is very low, around 23%. 100 planted in 2002.
Tecoma stans
(Bignoniaceae)

Yellow elder (candelillo) Tecoma Standii Candillilo Dec 02 Lower montane (1500-2300m), montane canopy species. Source: Smithsonian   See also the "Manual de la Flora de Costa Rica" ( Mobot ).  Catalpa family. 300 planted in 2002.
Persea caerulea (Lauraceae) Laurel (aguacatillo) Persea caerulea:  Laurel Aguacatillo Aug 02 Montane (2300-3200m) canopy species. Source: Smithsonian . As the local name suggests, this is a type of wild avocado tree, attracting quetrzals and other birds and animals. There are several varieties, three of which have been planted on Cloudbridge. 350 planted in 2002
Manilkara zapota
(Sapotaceae)
Nispero Manilkara zapota: Nispero Aug 02 Nisperos, we are told, do not need particularly good soil to thrive. In addition, they grow better in flatter areas rather than along slopes, so we planted most if not all the Nisperos in the lower sections. The accuracy of the seedling identification on the right is in doubt. 250 planted in 2002.
Ulmus mexicana
(Ulmaceae)
Elm (tirra) Ulmus mexicana: elm, Tirra Aug 02 Can be seen in surrounding forest. "These trees make many seeds and are easily germinated and planted in one year unlike many native trees which must grow for two years before planting. This tree grows fast and well on slopes." Many of the ones we planted were very small but with care have survived and now look healthy. 400 planted in 2002.
Cedrela tonduzii
(Meliaceae)
Sweet cedar (cedro dulce) Cedrela tonduzii: Sweet cedar, Cedro dulce Aug 02 "It grows best at 1200 meters above sea level. Grows very fast and is locally used for cabinets, furntiture etc. A beautiful pink colored hardwood, extremely easy to work. The only danger is a shoot-borer pest commonly called a "mariposa"  (hypsipyla grandella) which is a worm of sorts which bores into young saplings under two years old. You have to keep a close eye on these saplings and refrain from planting them in any plantation context. Mixing them in among other trees helps to deter the pest," but they may need a "poda" (see below) or special mulching if any signs of infestation appear. 500 planted in 2002.
Cupressus lusitanica
(Cupressaceae)
Cypress (cipres) Cupressus lusitanica: cypress, Cipres Aug 02 "Grows very well at elevations exceeding 1200 feet. Studies of high altitude trees by Freddy Rojas at the Instituto Tecnologico de Costa Rica suggest that Cipres is the tree most suitable for growing in plantations at high altitudes." At year one, these Cypress trees will need special maintenance referred to as the “poda” when the lower branches are trimmed to within 45% of the entire tree height.  550 planted in 2002.
Alnus acuminata
(Betulaceae)
Alder (jaul) Alnus acuminata: alder, Jaul Aug 02 Lower montane, montane. Good for nitrogen-fixing; it is perfect for planting in eroded areas or areas suffering from deforestation. It is also a  fast-growing commercial tree producing a semi- hard, almost golden colored wood. The fruits are cone shaped and are green-yellow when immature and maroon upon maturation. Each cone contains around 100 to 125 seeds. The seeds are very small, elyptical shaped, and dispersed easily by the wind. 700 planted in 2002.
Billia hippocastanum
(Hippocastanaceae)

Cucaracho
Billia hippocastanum: cucaracho Seen on the trail to Chirripo, at a Cloudbridge altitude.

Papayillo, papaya
This is a shade-intolerant, slow-growing tree and is commonly found in dwarf forests on wind-swept ridges or, in its hemiepiphytic form, growing high in cloudforest trees. Lower montane (1500-2300m) canopy species. Source: Smithsonian

SHRUBS AND OTHER SPECIES
Citharexylum Donnell-Smithii
(Verbenaceae)
Dama, juniper berry
Citharexylum caudatum: juniper berry, Dama Aug 02 A fruit tree. Damas are said to serve as effective windbreakers. Several have been identified throughout Cloudbridge especially along the right side of the trail leading up to the planting sites. "Large shrubs or small trees up to 20 m tall; branches nearly terete, glabrous. Leaves somewhat leathery, oblong to obovate or elliptic-oblanceolate, 7-16 cm long, 3.5-5 cm wide, glabrous, upper surface glossy, lower surface dull, apex rounded or obtuse, base cuneate, petioles green, 1-2 cm long. Flowers in narrow, elongate-recurved racemes 4-10 cm long, pedicels usually 2-5 mm long; calyx campanulate, ca. 3 mm long, the rim unlobed and truncate in fruit; corolla white. Fruit purplish black, oblong-globose, ca. 5-8 mm long." (Wagner et al., 1999). Source: PIER . See also USDA . 300 planted in 2002.
Tournefortia volubilis
(Boraginaceae)


Frutilla Tournefortia volubilis: Frutilla Aug 02 A fruiting shrub. Planted to encourage birds and add diversity. Source:

150 planted in 2002.
Erythrina poeppigiana Poro, flame tree "Fence-post tree" with excellent nitrogen-fixing qualities. Leguminous. Can be propagated by cutting a branch and planting it. See Planting by estacas .
Spondias purpurea
Jocote
This tropical fruit tree indigenous to Mesoamerica can also be propagated by branch cuttings. See Planting by estacas .
Chusquea spp.
(Poaceae)
Bamboo Several species of bamboo grow in the high-altitude understory, and dwarf bamboo prevails in the paramo. We have used it alongside the road and as stakes for the trees. Bamboo is used to stem soil erosion at lower altitudes. We have considered using native bamboo, found in the adjacent forest, to shore up eroded areas. However, with the cows gone, the grass is rapidly securing this area so we're leaving it alone. For info on a local, albeit low altitude, bamboo plantation see: http://www.idccr.com/
