Guanacaste (also known as Parota) is a fast growing, medium to large tree with a massive crown occurring in Central America. 50 years old tree can have 100-130 cm diameter of trunk. But normally tree has short trunk, its slpits on many branches and we can get log with length 2,5-4m.
Heartwood is light to medium brown, sometimes with a reddish hue. Darker streaks of brown are sometimes present. Sapwood is pale yellow and is clearly demarcated from the heartwood. The wood texture is very rough with a mild natural shine.
Guanacaste has very large pores in no specific arrangement, very few; mineral/gum deposits occasionally present; parenchyma vasicentric, confluent; narrow to medium rays, spacing wide.
Workability: Easy to work with hand and machine tools. However, tearout is common during planing, and fuzzy surfaces may be seen after machining, especially on quartersawn surfaces. Glues and finishes well.
