This unit, part of the Nature of Teaching series, explores the effects of barriers and human assistance on wildlife gene flow. Students will learn about the effects of human-induced factors on wildlife movement and gene flow, and the effectiveness of human interventions that promote gene flow among wildlife.  You will find in the complete curriculum: teachers’ notes, vocabulary words, objectives and required materials for activities including gene flow simulation and estimating genetic variations in lady beetles.

The Nature of Teaching includes formal standards-based curricula and informal activity-based curricula all centered around getting youth outside. The three program areas of the formal curricula include: Wildlife, Health and Wellness, and Food Waste. Each program area provides standards-based lesson plans free as a downloadable PDF. Lesson plans are classroom ready for grades K-12.

Did you know that the majority of tilapia grown in the Midwest region of the United States are sold live in ethnic markets? And the majority of tilapia eaten in the United States are imported from Asia and Latin America?

Farmed tilapia is considered safe to eat. In fact, they are identified as a “Best Choice” fish for pregnant women, breastfeeding mothers and children according to the EPA and FDA.

This publication, “Tilapia Farmed Fish Fact Sheet“, is the third in a series of consumer guides that describe fish and shellfish farmed in the Midwest region of the United States. The fact sheet also includes culinary characteristics, cooking tips and a recipe for Sauteed Tilapia.

To view other consumer guide publications and video resources, check out Purdue Extension’s The Education Store website.

As trees grow and reach heights which many consider to be unsafe, tree owners would often top their trees by reducing the tree size. This is by heading back most of the large, live branches from the tree. However, topping trees proves to be more damaging than beneficial.

Topping trees can cause decay, weak branch attachments, and an increased likelihood of failure. If we do not top our trees and leave them to develop naturally, the structural strength of the trees is stronger than those that are not topped. The extensive root system, when left undisturbed, provides adequate support for the trees.

This publication titled What’s Wrong with Topping goes in-depth on the implications of topping and provides better alternatives to topping.

Spring is here! It is the time of year for some of us to be planting new trees. In this Ask an Expert session, we welcome Lindsey Purcell, urban forestry specialist, as he teaches us how to plant and properly care for our trees. He goes over the tree selection process, including which invasive species trees we should avoid, and how to continue to take care of our trees once planted.

If you have any questions regarding wildlife, trees, forest management, wood products, natural resource planning, or other natural resource topics, feel free to contact us by using our Ask an Expert web page.

Join Lenny Farlee, Purdue FNR Extension Forester, as he explains why the typical thinking of what is a tree and what is a shrub isn’t always simple as far as looking for the “single” trunk to call it a tree. There is some crossover. Lenny shares the different ways to identify if it is a shrub and then the various species in Indiana.

Question: Can I plant grass over soil where a newly removed stump was ground out?

Answer: We generally don’t want to plant new trees or turf immediately over the top of existing stumps in landscapes. The reasoning is a bit complicated but somewhat simple. The stump location will have limited soil and rooting depth for nutrient uptake and structural stability due to its remaining below ground mass.

The woody debris material created from stump grinding has a high carbon to nitrogen (C:N) ratio. This reduces nitrogen availability for the new tree or grass. Also, there will be significant settling of the ground below the stump as it decays and loses its structural fiber. The soil should be added to replace the below ground roots and stump. It can take several years to fully decompose the stump unless it was ground very deeply or removed with an excavation machine.

The recommendations are adding soil to the stump area, and a little additional soil mounded to compensate for some decay. Plant the grass, preferably sod, however, seed can work, to adequately cover the newly exposed area. Be sure to add slow-release turf fertilizer to compensate for the high C:N ratio that will be robbing nutrition from the newly installed turf. Maintain adequate moisture and look for signs of yellowing, indicating low nitrogen levels.

Also, sprouts may be generated due to the roots acting as energy storage for the tree. Simply treat them with typical lawn herbicide as needed at the label recommended rates.
