Botanical Supplies I Use

Click to see a bibliography of the books I rely on for plant identification and for much of the other information I present on this website.

Click for books about plants from a company that donates to Native Plant Societies.

Several years ago I made a wildflower app. and I think you will enjoy using it. Click for "Colorado Rocky Mountain Wildflowers".

Keeping Track of Your Naturalist Findings
Click for the Bird/Flora/Mammal Diary. Free 30 day trial.

Hand Lenses (Loupes)
Hand lenses are essential for identifying plants and they add to your enjoyment of the beauty and intricacy of plants.

A 10x (magnifies 10 times) is all you need. Higher magnification hand lenses have a smaller aperture, less depth of field, and in general are much more difficult to use.

A lighted lens sounds like a good idea; it isn't. A lighted lens is heavier and is of no use. Use the sun outdoors and a high wattage lamp at home.

I use a Belomo 10x hand lens.

Click for a nice, $5, easier to use hand lens for kids.

The Bausch and Lomb 10x triplet is also very good
and it is available from many online sources.

Click for other hand lenses

Field Gear

For superb day packs, my wife and I use Osprey Packs.

I shoot all my photographs with a Sony RX-10, which, although not an SLR, does give me full manual control, through-the-lens viewing, a macro down to one cm, and an excellent Zeiss lens. I highly recommend this camera.

I carry the camera on a harness system so it is comfortable to wear all day and at hand all the time.

I am happy to answer questions about any of the above products: email me.
