A menos que ya esté muy familiarizado con los árboles en su área, tendrá que obtener una guía de campo sobre los árboles para esta actividad. ¡Ilustrar todas las especies de árboles que pueden surgir es mucho más allá del alcance de un solo capítulo en este libro de respuesta!
Lo mejor es recoger las hojas en la primavera o principios del verano antes de que los insectos y el tiempo hayan tenido la oportunidad de dañarlas. Pero, si lo prefiere, puede tratar de recogerlas en el otoño, cuando los colores cambian.
When you go out collecting, take the field guide with you. It is important to identify the leaves as you collect them, as you can look at more than just the leaves for identification. The bark, environment, buds, and shape of the tree are all important clues to the tree's species. This is especially important if you wish to differentiate trees of the same genus (such as black cherry, pin cherry, choke cherry, etc.). Indeed, proper identification may not be possible from just the leaf.
Collect leaves that are typical for the tree, but remember - smaller leaves are going to be easier to fit onto an 8.5x11 inch sheet of paper.
Press the leaves by placing them on some sort of absorbant paper - newspaper, paper towels, tissues, etc. Then place these under a stack of books or in a leaf press. After two weeks, the leaves should be flattened, dried, and well-preserved. Evergreens such as spruce and fir are difficult to preserve this way as the needles will fall off. The more ambitious may wish to encase the leaves in epoxy, as this preserves the color and eliminates the need for pressing (meaning the leaves also retain their three dimensional features).
Una vez que las hojas se han prensadas, se pueden pegar, poner con cinta adhesiva o laminar en papel de cuaderno. Utilice hojas sueltas si desea cambiar sus posiciones después. También puede colocar las hojas prensadas entre dos hojas de papel encerado, cubrir con una toalla y plancharlas.
