Good read..... It's a FB post from a site called Bayou-Diversity
Bayou-Diversity (4 February 2024) LACASSINE VISIT More than forty years ago I was a fledgling wildlife biologist on one of the most spectacular wildlife areas in the country. Lacassine National Wildlife Refuge, comprising almost 35,000 acres in southwest Louisiana, contained some of the most beautiful, biologically rich, freshwater marshes anywhere. Established in 1937, more than 3,000 acres of natural marsh is an officially designated Wilderness Area, but the jewel of this national treasure is Lacassine Pool, a 16,000-acre impounded and managed marsh. During my tenure one could stand on the levee of Lacassine Pool on a winter evening at sunset and observe a wildlife extravaganza unique in North America, as more than 700,000 waterfowl flew in and out of the Pool on foraging missions. The sensory overload of such scenes evoked in me the idea that this is what pristine nature looked like before humans altered our world for good.
A few years ago I had an opportunity to revisit Lacassine National Wildlife Refuge and ponder three decades worth of changes. Nothing in the natural world is static, and some of us who occasionally long for the good old days should know better. We realize that natural phenomena, such as plant succession and wildlife population fluctuations, are normal. Even the changes caused by Hurricanes Rita and Gustav are natural in the long-term scheme of things. It’s the negative human-induced changes, intentional or otherwise, that stick in the craw.
Gliding down the bayou that transects the refuge in a bateau, the first thing that jumps out at me is that the marshes look weedier. Chinese tallow trees, which have been here a long time, are now more abundant and have been joined by new insidious, invasive species like common salvinia and witch grass. They take the places of native plants and are up to no good. A hundred foot oil-drilling derrick rises up out of the pool, something that formerly never occurred in winter when ducks and geese were a priority in an inviolate sanctuary. Instead of a million waterfowl, we see a few thousand, which has been the norm for a while, and yet the hunting seasons are longer and the bag limits more liberal now. The birds are not somewhere else, as some believe.
We saw positive changes too: fewer exotic nutria, more roseate spoonbills, a prairie restoration project, and a new wildlife drive. Overall though, the biological integrity of Lacassine has declined both because of and in spite of human actions—an ominous dividend of the political, economic and social trends in recent years.

Kelby is correct. I followed Kelby at Lacassine as Asst Refuge MGR. . i personaly observed between 500K and 750K ducks and geese on aerial surveys observed by me and verified by LDWF ON Lac Nwr. More recently those numbers are usually less than 50k. poor regulations allowing high limits and long seasons have decimated nesting ducks on severely impacted prairie pothole nesting areas. results are recorded in official USFWS DATA. LOWER breeding populations and severely reduced harvests.

Some of the younger adults coming along simply don't have as long a personal experience with spectacles of avian abundance and diversity. In the 70's and 80's, when I was a young adult and an avid birder, evenings especially, near most Louisiana wetlands of any decent size, both North and South, there would be many lines and V's of ducks in the sky. Now...not so much. It's not the same, at all. In the least. Many happy hours spent birding the Southwest LA marshes from Lake Charles to Cameron and Holly Beach, over to Creole and Abbeville. Ducks by the million, far as the eye could see. Later, was fortunate to be appointed to the White Lake Commission, and for several years, heard and participated in the in's and out's of managing a wonderful publicly owned coastal wetland and balancing the needs of the resource, and the public need for harvest. Hubby was until recently a once-avid public lands duck hunter. Last few years, there have not enough ducks in NELA for him to buy new waders every other year. We live shouting distance from Big Branch National Wildlife Refuge at our fishing camp, and raise Wood Ducks in our boxes, both north and south, every year. We've had as many as 200 Wood Ducks visit our 2 acre pond in North LA, at one time, in recent years. And we remember when seeing a Wood Duck was a "write up" bird, for the Louisiana Ornithological Society records, their populations had declined so much because of irresponsible pesticide use. Theirs is a recovery story that other duck species have not shared. So I'm not just some old lady spouting an uninformed opinion. Kelby knows what he is talking about, even more than I do. Listen to him, and heed his words

I feel the day and age of unlimited (other than bag limits) public waterfowl hunting is coming to a close. Private waterfowl hunting preserves limit the number of hunts and hunters, via high $ fees, or, limited to landowner & guests. That might be what public hunting opportunities will need to consider, sooner or later. Birds that experience daily pressure, move elsewhere.

Bayou-Diversity I’m afraid the waterfowl resource isn’t managed anymore to provide maximum population. Rather maximum hunter satisfaction and days afield. Mallard population has declined from 11.793 million breeding pairs in 2016 to a low of 6.1 million in 2023. Yet here we are still in liberal season framework.
Kelby Ouchley
Scott Cararas It was never a goal to manage for maximum populations (If that was the case, any hunting would be counter-productive), but rather to regulate for sustainable ones at high levels. Sadly, the politically driven regulations of the last 30 years have yielded anything but sustainable populations. And you are right; here we are with plummeting populations and liberal regs.
Scott Cararas
Kelby Ouchley there is a camp of biologist that say harvest doesn’t affect population. I don’t totally agree, especially when you have a low population, it definitely hurts to send back less to nest. You are spot on about the regs being politically driven.

Scott Cararas Yes, that old school thought of compensatory mortality is taking a heavy hit these days.

Your story while moving and in some ways correct has many errors.
The ducks are still here in the millions.
There are just more pools for them to gather in . Refuges created and expanded after Laccasine.
And the oil drilling is not new.
It has been continuously done since before the pool was donated by the oil company.
I am a regular visitor to all the areas and a certified Master Naturalist !

Thomas Morris I'm afraid LDWF & FWS biologists conducting aerial surveys and ground truthing would beg to differ with you regarding your declaration of "millions." And so would the bulk of duck hunters in that area. As for the oil drilling, you are correct that it was ongoing before the refuge was established. However, drilling in the pool was very restricted during the period of time when wintering waterfowl were present.
Thomas Morris
Bayou-Diversity if you go to the Federal reserves at pintail loop and The west pools there are millions of ducks.
We have pictures of the pools thick with ducks and the skies so crowded you can barely see sky.
This after a devastating drought and planned drawdown for weed control.
And our Master Naturalist group includes multiple LDWF field agents and biologists who would disagree with your assessment .
I live here. Where do you live.
Is your observation based on a single trip to one pool.

Thomas Morris Southwest Louisiana – 716,000
The estimate for southwest Louisiana is 56% above the December estimate of 458,000, but 42% lower than last January’s estimate (1.23 million), and 39% and 46% lower than the most recent 5-year, and 10-year January averages, respectively for the region. For the first time since 2015, the January duck estimate in southwest Louisiana was lower than the southeast marshes (Figure 3). Gadwall and green-winged teal were the most abundant species in the southwest, together making up 52% of the duck total.
