Discover how to manage non-native cool-season grasses like tall fescue and Kentucky bluegrass in native conservation plantings. This guide reveals how these invasive species form dense sod layers, which limits wildlife mobility, and also provides control options for these invasive species. Controlling Introduced Cool-Season Grasses is essential for anyone dedicated to preserving native ecosystems and enhancing biodiversity.
Check out the Managing Conservation Plantings Series which include details on how to control invasive species and other problematic plants in Conservation Reserve Program (CRP) plantings and native warm-season grass and wildflower conservation plantings.

Once the leaves have fallen and the landscape is dominated by shades of brown and gray, bright colors like red catch our attention. There are several red fruits that we may encounter in the late fall and winter here in Indiana that add some color to the landscape. These fruits are retained on trees and shrubs for a variety of reasons. Some are not as palatable to wildlife, so they are eaten later in the season. Some are more resistant to freeze damage and thus cling to branches longer than delicate fruits. There may also be an advantage to their appearance. Many of these plants have seeds dispersed by wildlife like birds, which eat the seeds and excrete them later, providing an opportunity to produce new plants away from the parent. Many birds can see much of the same color spectrum we do, plus enhanced vision in the ultra-violet bands. Brightly-colored seeds with waxy skins may reflect more ultra-violet light and be more noticeable to the birds.
What are some of those red fruits?
One family of plants accounts for several red fruit we can see in late fall and winter, the rose family. This family includes apples, plums, cherries, hawthorns, pears and others as well as the roses. In Indiana we have several hawthorns (Crataegus species) that produce a fruit resembling a tiny apple. These vary in size by species but are typically ¼ to ½ inch diameter and often held in clusters. Hawthorns are typically small trees and may have long thin thorns on the twigs.
Another rose family member are the apples and crabapples with some small native trees like sweet crabapple, Malus coronaria, and several varieties of fruit-bearing apples and ornamental crabapples planted but sometimes escaping to natural areas. While our native crabapples are usually about 1-2 inches diameter and green to yellow, the domesticated apples and crabapples often have red fruit in various sizes from large apples to ½ inch diameter crabapples.
We also have several beautiful native roses in Indiana, and a particularly problematic exotic invasive rose in multiflora rose. Unfortunately, you are more likely to encounter multiflora rose with small ¼ inch clusters of red fruit. Our native roses typically have larger fruit and fewer fruit per cluster.
Holly is also noted for red fruit and some being evergreen as well. Our native Indiana hollies are all deciduous, losing their leaves in the fall but often retaining the red fruit on the female plants into winter. The most widespread species is winterberry, Ilex verticillate, a shrub which is seeing more use ornamentally due to its striking red fruit held past Christmas most years. American holly, an evergreen broadleaved tree, is well-known for its glossy, spiny foliage and red fruit on the female trees. Although not native to Indiana, it is spreading from plantings into natural areas. Several evergreen hollies from Europe and Asia are also common in ornamental plantings and may escape into natural areas.
Not only are these late-season showy fruit attractive, but they also provide some important nourishment for wildlife when the many other fruits are long-gone.

The Purdue FNR extension team was named as a recipient of the Family Forests Comprehensive Education Program Award presented by the National Woodland Owners Association (NWOA) and National Association of University Forest Resources Programs (NAUFRP).
The award, which is the nation’s top honor for forestry extension programming, recognizes superior performance across nine rigorous criteria, celebrating the standard of excellence for the profession. Drs. Zhao Ma and Mike Saunders received the award on the team’s behalf at the NAUFRP annual meeting at the 2025 Society of American Foresters (SAF) national convention in Hartford, Connecticut, in October.
The Family Forests Comprehensive Education Program Award criteria includes:
NAUFRP extension chair Bill Hubbard, who oversaw the competition said “After a thorough review by our three judges and myself, the committee determined that both the University of Minnesota and Purdue University programs demonstrated such profound and differentiated excellence across the nine core criteria that it was decided to recognize them both.”
According to the NAUFRP announcement, “Purdue’s program was honored for its massive scale, its deep connection to a long-term research asset, and its commitment to building future workforce capacity.”
Program highlights include:
The Purdue team includes five faculty and nine professional staff members. Over the past five years, the group boasts many standout accomplishments including:
In the nomination packet, team personnel stated “We aim to address family forest owner needs through collaboration with many stakeholders. Our family forest education serves family forest owners, professional advisors, an industry that receives most of their product base from family forests and the general public who influence policy decisions affecting family forest owners. Our program focuses on adoption or maintenance of stewardship practices (e.g., invasive plant control, timber harvesting), developing or improving forestland planning, and engaging peer and professional advice. In doing these, family forest owners can make informed decisions that meet their personal land management objectives while enhancing the resource for all residents.”
Team members include:
From 2020 to 2024, the FNR Family Forest Education extension team conducted 788 programs, covering 1,005 sessions and including more than 50,000 individual contacts.

MyDNR, Indiana’s Outdoor Newsletter: There are many options for enjoying outdoor recreation across Indiana this fall, especially with deer hunting season upon us. Learn more about deer hunting, how to support healthy wildlife populations, important regulations and how your hunting can support Hoosiers in need. Pay special attention to deer regulation changes, season dates and the importance of purchasing your license.
Deer Hunting Regulation Changes
Indiana DNR has made big changes to Indiana’s deer hunting rules. These changes are in effect for the 2025-2026 hunting season. The changes were made, in part, to make Indiana’s hunting regulations easier to understand.
Rule changes include:
For questions about equipment, regulations or changes in them, or which license you need, contact the Deer Information Line at INDeerInfo@dnr.IN.gov or 812-334-3795.
View a webinar recording explaining deer regulation changes.
Hunting Safety Tips and Reminders
Indiana DNR reminds you to stay safe this deer season. Hunting injuries most commonly involve elevated platforms and tree stands, so stay safe by following the guidelines below.
Tree stand safety before the hunt:
General reminders:
Always bring emergency equipment with you on your hunt, such as a cellphone, flashlight, small first aid kit and extra water.
Read more about the guidelines and property rules here: Fish & Wildlife Properties.
Deer Reduction Zones
For information or any questions, view: Deer Reduction Zones.
Deer Disease Updates
Chronic wasting disease (CWD), a fatal disease impacting white-tailed deer, has been detected in wild deer in two areas of Indiana: LaGrange County and Posey County. These detections resulted in a CWD Positive Area including LaGrange, Noble, Steuben, and DeKalb counties and a one-year CWD Enhanced Surveillance Zone including Posey, Vanderburgh, and Gibson counties.
DNR offers free, statewide CWD testing for hunters by either taking your deer to one of DNR’s drop-off coolers at select Fish & Wildlife areas (FWAs), state parks, state fish hatcheries (SFHs) or through advertised private businesses such as taxidermists. These options are available during all seasons. Find out more about how to get your deer tested here: Chronic Wasting Disease (CWD).

Several things come into play when it comes to determining the colors that we find on leaves of our trees. As our days get shorter and our nights get longer there is a chemical change that happens in the tree. In this video Lenny Farlee talks about the several pigments that are found in trees and what changes from summer to fall that brings us the bright colors on leaves.
Explore IndyStar Story Behind Our Fall Colors
