HBEC Eagle Day 2015

Once again this year we have had the blessing to watch two more Bald Eagles hatch and grow thanks to our Harrison Bay Eagle Cam and all of our great viewers, chatters, sponsors and donors. We have always held to the belief that a golf course is more than just a place to chase a little white ball around and put it in a hole.  Golf courses are a fantastic sanctuary for wildlife, insects, plants, and especially, birds.  Our camera gives us, and anyone else around the world, an upclose view of the life and struggles from breaking out of the egg to taking that first leap of faith and launching into the wind to soar free.

 This past Tuesday we got to welcome just a few of the people who have logged on to view the eagles this year when we held our first annual HBEC Eagle Day at Harrison Bay.  In 2011 when we started this project I would not have imagined that it would have gathered such a loyal following or would have brought so many different people from different parts of the nation together, but it has.  Each Tuesday morning we have a nest tour for the locals who want to come view the eagles from the ground but not everyone who watches the camera is local. So, with the help of our moderators, we put together a date when people outside of our local viewing area could come to the course to see the eagles.

The festivities began on Monday night where many of us met, some for the first time, at the Harrison Bay rec hall for a "meet and greet". With over 50 people in attendance from 9 different states we had the great opportunity to watch Harrison Bay State Park Ranger Matt Vawter give us a demonstration of Scarlett, a red tail hawk who is a resident at the Harrison Bay SP Raptor Center.  Scarlett is blind in one eye and so she can not be released into the wild but she has a great home and does wonderful educational programs at Harrison Bay.

One of our moderators, affectionately referred to as PTomahawk, brought this specially decorated cake for the event.  Not sure who to give credit for the skill and creativity but it is amazing.

Special appreciation has to go to the Friends of Harrison Bay State Park for providing food and drinks at the "meet and greet" as well as for the moderators lunch on Tuesday.  Wonderful group of people who have supported, sponsored, and encouraged the eagle cam from the beginning.

Sadly, not everyone that wanted to attend Eagle Day could make it so we turned the camera on some of the visitors so they could wave at all their HBEC friends.  It was nice to see people who had chatted together all year meet each other and put faces with names.  Our eagle cam is like a little family spread out all over the world.

Watching Elliott and Eloise raise their young each year has truly been one of the highlights of my career.  There is a special sense of pride and responsibility in keeping their "home" safe for them and their young and we take that very seriously.  I hope that we will continue to be blessed by these magnificent creatures for many years to come and I hope you are able to get a glimpse of them when you are on the course.

Remember, golf courses are for more than just playing golf.  Take a look around next time you play and take in all the course and the environment has to offer.

Summer has finally arrived for us and while many people are going on vacation or laying out by the pool for the managers of ultradwarf bermudagrass greens the work is just beginning. Speaking for myself I can say that I love my job. I love being outside, seeing the sun rise each morning, watching the wildlife play on the course, and I even like the challenges that comes with my chosen profession.  One of the biggest challenges that we, golf course superintendents, face is finding the balance between the expectations of golfers and the health of the turfgrass, especially when it comes to putting surfaces.

For managers of the new ultradwarf bermudagrass cultivars that are replacing bentgrass greens all over the south thatch accumulation is probably one of our biggest issues.  Thatch according to the dictionary is "a tightly bound layer of dead grass, including leaves, stems, and roots, that builds up on the soil surface at the base of the living grass of a lawn."  Thatch according to a superintendent creates soft, patchy greens which are slow, can easily be scalped, harbor insects and disease pressures, and restrict the inflow of water, air, and nutrients.

The greatest tool that we have in combating the excessive accumulation of thatch is the use of vertical mowing or verticutting.  This is a process of using blades which are positioned vertically to slice through the surface and raise/remove growth which is not removed during normal mowing operations.  Is thatch a big issue?  Well the picture to the left shows the material removed from a single 10,000 sq. ft. putting green.  If this material is not removed on a regular basis the greens will become soft and puffy and will not be an acceptable putting surface and will eventually fail to perform correctly.

Our practice for the past two days which we called "Verticutapalooza" because it was a party for both us and the greens was to vertical mow up one direction and then back down the same line with the blades set 1/16" below the rollers. This picture shows on the left the green surface following the verticutting practice and on the right the greens surface once it has been mowed with our normal cutting units.  The thatch that was removed and the excess growth that is cut off of the surface helps to provide a firmer, faster, and more consistent putting surface.

Once the greens were mowed they were topdressed fairly heavily with a kiln dried green sand which was then drug into the surface with a carpet drag mat.  The incorporation of sand to the surface helps in the breakdown of organic matter in the soil matrix, fills in any voids in the putting surface, and helps to aid in the infiltration of water.

We use kiln dried green sand for our topdressing sand because it mitigates some, if not all, of the concerns and/or complaints by golfers of the greens being topdressed.  Many golfers are under the misconception that a green which has been topdressed will be slow, bumpy, or will drastically interfere with their round.  A light application of topdressing sand will actually make the greens smoother, faster, and more consistent but the sight of a green topdressed with white sand, no matter how well worked in, will still cause some golfers to complain to the proshop.  With our green sand if you don't see us putting it out you are most likely not going to be able to tell the greens have been topdressed and in our mind is worth the extra cost.

This is a picture of #18 green after being verticut twice along the same line, mowed, topdressed, and drug.  A massive amount of material was removed from the putting surface but it will only go to help the green both in the short term and the long haul.  Some golfers may see agronomy departments verticutting greens and think "They are destroying the greens.  Why can't they just leave good enough along?"  We could but the putting surface would not be the best it can be and would eventually begin to fail, resulting in lost turf and extensive restoration of the surface. Basically it is a very short term, minimal disruption for the overall longevity of the green.

May was a very busy month for us with 21 outings and tournaments which limited the amount of cultural practices we were able to perform to the greens.  We will resuming our biweekly verticutting program starting next week so that we can continue to improve our putting surfaces in an effort to provide the best putting surface we can for our golfers and guests.  Some had questions about what we were doing to the greens and I hope this has helped to alleviate some of those questions and concerns.
