American Midland Naturalist, 1976
Eight families and at least 30 species of spiders were col- lected from young black walnut (Juglans nigra L.) trees in southern Illinois. Four species are new state records. Previous spider faunal studies of North American trees are summarized. Six species found on black walnut have habitat associations with six or more other tree species.

Black walnut toxicosis in ten horses
Journal of the American Veterinary Medical Association, 1989Black walnut toxicosis was diagnosed in 10 horses at one stable. The time from exposure to shavings to development of clinical signs was 8 to 12 hours. Most common clinical signs were moderate to severe laminitis (Obel grade 2 or 3), pitting edema of the distal portion of the limbs, and rapid respiratory rate. Two horses had clinical signs of colic and

Black Walnut Extract: An Inflammatory Model
Veterinary Clinics of North America: Equine Practice, 2010The black walnut extract (BWE) model was developed after the discovery that horses bedded on shavings from black walnut trees commonly developed laminitis. The first investigators that consistently induced laminitis with black walnut shavings established that it was only the heartwood of the tree that induced laminitis.

Black walnut induced laminitis.
Veterinary and human toxicology, 2000A 5-y-old Paint horse gelding was evaluated for acute laminitis after exposure to black walnut shavings. The gelding's feet were previously soaked in an ice bath continuously for approximately 24 h. Treatment consisted of anti-inflammatory and vasodilator therapy.

Making syrup from black walnut sap
Transactions of the Kansas Academy of Science, 2006Abstract Experimental tapping of black walnut (Juglans nigra L.) trees has shown that there is a substantial amount of sap flow in young black walnut trees and that it can be tapped and processed for the making of sugar syrup. It also shows the importance of a wide sapwood ring in obtaining a good yield of sap.

Black Walnut Provenance Performance in Kansas
Northern Journal of Applied Forestry, 1992Abstract Fifteen seed sources of black walnut were planted at Manhattan, Kansas (39.2°N and 96.5°W) in 1967, the western edge of its natural range. After 22 years, height, dbh, and survival measurements revealed that local trees (Kansas) and trees from within 200 miles south of the planting site grew tallest.
