Trees Pacific NW highlights the easiest-to-spot distinctive features of each tree.


What are the advantages of this app?

1. Compared to a book, you are more likely to have Trees Pacific NW with you, in your pocket.

2. Using this app, you can learn to recognize a tree by its most obvious distinguishing features. These features are different for each species. Tree books are not organized this way.

3. In Trees Pacific NW, you can examine the trees in a number of ways. You can go directly to any of these categories:

  • #1 Tree
  • Top 10
  • Conifer
  • Broadleaf
  • West side
  • East side
  • Coastal
  • Low elevation
  • Mid elevation
  • High elevation
  • All trees
  • Favorites

In contrast, books are organized in a single predetermined order.

4. Trees Pacific NW contains a number of "Compare" links. By tapping on these links, photos of the same feature (e.g., the bark) on two or more trees will pop up. This allows you to compare easily.

5. In the app, over 100 terms have links directly to a glossary. Just tap on the word or phrase to get the definition.

6. In the app, there are FAQs such as “What is forest succession?” or “How do trees draw water all the way up?” These FAQs are links. Tap the link to read the explanation.

7. The photos in Trees Pacific NW are higher-quality than in typical tree books.

Why is this app useful?

Most books about trees are organized by a fixed sequence of information for each tree, such as this:

  • whether the leaves are "opposite" or "alternate"
  • whether the leaves are "simple" or "compound"
  • the shape of the leaves
  • a description of the twigs
  • a description of the bark
  • a description of the cones or flowers
  • etc.

But the easiest-to-spot distinctive feature of one species may be its bark, while the easiest-to-spot distinctive feature of another species may be its cones or needles or branches. Trees Pacific NW provides a customized approach for each tree species.

Trees Pacific NW helps you learn about native trees of the Pacific Northwest by their most-obvious features, the same way you recognize your friends, your dog or cat, or your car.

Once you learn the basics, you can choose to dig more deeply. There are additional photos, links, and discussions to increase your understanding.
