The Signs of the Presence of Resin in the Oud Tree

After the seeker recognizes a tree of the producing genus, the most important question remains: does this tree actually bear resin? For the correct tree may be entirely empty of oud. Here begins the stage of reading the signs of the presence of resin: external and sensory indications the explorer reads to make it likely that the tree is worthy of close inspection. In this article we present these signs in general terms, with the emphasis that they make it likely and do not prove it, and that the final judgment comes only by opening the wood.

Why do the signs appear in the first place?

To understand the signs, one should recall how oud forms. For it does not arise in healthy wood, but forms in response to a wound or an infection that pushes the tree to secrete the dark resin in the injured area, a mechanism we explained in detail in the science of oud formation, and whose relation to wounds we addressed in the role of wounds in oud formation.

And so the signs the explorer looks for are, in essence, the traces of this old injury: a place where the tree was subjected to a wound, a break, or decay, so that the process of formation began around it. For the external sign is not the oud itself, but a trace that may indicate that the tree has passed through what may have created oud within it.

External signs on the trunk

Among the most prominent of what the seeker reads on the tree from the outside: a local deformation or swelling in the trunk or the branch, traces of old wounds or breaks, sites of decay or rot, and sometimes traces of insect activity around a particular spot. That may be accompanied by a local change of color in the exposed wood, or the appearance of dark veins where the concentration of resin is expected.

And we emphasize that these signs are read together and in their context, not singly. For the presence of an old wound in a tree of the producing genus raises the likelihood, but it does not guarantee anything; the wound may have created no resin worth mentioning, and the oud, if present, may be scant or scattered. And the experienced seeker weighs between the strength of the sign, its location, and the state of the tree before he decides.

Scent: the truest of the initial indications

Among the strongest things the seeker relies on is scent. For when he scrapes part of the bark or opens a small incision in a likely spot, a woody, resinous scent may waft that indicates the presence of resin nearby. And this cold scent — before any burning — is among the truest things the people of experience rely on in the initial estimation, because it emanates from the resin itself, not from an external appearance that may deceive.

But even the scent remains an initial indication, not a precise measurement. For its strength and its character give an impression of the nearness of the resin and perhaps of its richness, without settling its amount or its grade. And the precise estimation of value comes later, after extraction and sorting, which we detail in later axes of this guide.

From the sign to the decision

When the signs come together and make the presence of resin likely, the seeker stands before a decision: does he open the wood to make sure, or leave the tree? And this decision weighs between the strength of the signs, the cost of opening, and its effect on the tree. For opening is not without a price, and responsible gathering requires that trees not be opened indiscriminately on a mere weak guess, but where the signs make that reasonably likely.

And thus reading the signs leads to the next stage: opening the wood and extracting what is in it, which we detail in a later axis of this guide. And the gathering thread remains that the signs are a key to a likelihood, not a final testimony, and that local expertise is what translates them into a wise decision.
