PROTECT MONARCH BUTTERFLIES

PLANT NATIVE FLORIDA PLANTS TO PROTECT MONARCH BUTTERFLIES

Asclepius tuberosa, commonly known as butterfly weed, stands out as one of Florida’s native milkweeds. This bushy perennial, reaching heights of 1.5 to 2 feet, is celebrated for its vibrant, flat-topped clusters of bright orange flowers. The leaves, typically arranged alternately, measure 1-2 inches long, featuring pointed tips and smooth edges. The clusters of yellow-orange to bright orange blooms, spanning 2-5 inches in width, adorn the flowering stem, which is subtly hairy. These attributes make butterfly weed a popular choice in nurseries across the state. Thriving as a perennial in USDA Hardiness zones 3-10a, it produces its striking orange or yellow flowers from late summer to early fall.


Other native milkweed species include Asclepias amplexicaulis (clasping milkweed), Asclepias cinerea (Carolina milkweed), Asclepias connivens (largeflower milkweed), Asclepias curtissii (Curtiss’ milkweed), Asclepias feayi (Florida milkweed), Asclepias humistrata (pinewoods milkweed), Asclepias incarnata (swamp milkweed), Asclepias lanceolata (flower milkweed), Asclepias michauxii (Michaux’s milkweed), Asclepias obovata (pineland milkweed), Asclepias pedicellata (savannah milkweed), Asclepias perennis (swamp milkweed), Asclepias rubra (red milkweed), Asclepias tomentosa (velvetleaf milkweed), Asclepias variegata (redring milkweed), Asclepias verticillata (whorled milkweed), Asclepias viridiflora (green milkweed), Asclepias viridis (green antelopehorn), and Asclepias viridula (southern milkweed).


NON-NATIVE MILKWEED 

Many experts advise against the use of tropical and non-native milkweed (Asclepias curassavica), which is commonly cultivated in Florida. This species features clusters of orange, yellow, and red tubular flowers and can grow to a height of 2–4 feet and a width of 1–2 feet. Its leaves are oppositely arranged, ending in acute tips, and it possesses smooth, upright stems. Notably, it exudes a milky sap and serves as a larval host for Monarch, Queen, and Soldier butterflies.


Negatives of Non-Native Milkweed: 

A. It does not die back in the southern climate and is susceptible to a parasite. The parasite Ophryocystis elektroscirrha (OE) can lead to deformities, smaller size, mating impairments, and reduced flight endurance in monarchs. 

B. In the long term, it poses a threat to ecosystems, even if cut back to 3 inches in the fall after its leaves have been consumed, in an attempt to mimic winter die-back and curb OE parasite spread. OE accumulates in tropical milkweed plants over time, becoming increasingly detrimental to monarchs. 

C. Additionally, tropical milkweed can mislead monarchs into breeding when they should be preparing for migration.

Gil Smart (VoteWater) and Eve Samples (Friends of the Everglades) updated the February 26th Rivers Coalition meeting on how this year’s legislative session in Tallahassee was going as far as environmental issues are concerned. It wasn’t good news. Gil warned us last month: “If last year’s legislative session’s theme was facilitating sprawl, this year’s is sprawl on steroids.” And since the Republican-controlled legislature can pass anything it wants, at this point the only possible changes in the disturbingly-large number of bad bills in the pipeline are tweaks to the bills. With one possible exception. Some North Florida Republican legislators have voiced concerns about the Everglades water management process. South Florida Republicans haven’t yet, but if they notice the desertions they may be persuadable. The bills are HB 701 and SB 1120. Gil’s bottom line: “Right now the worst bills are all the pro-growth bills like ‘Blue Ribbon Projects’; House Bill 299 is on the House floor but Senate Bill 354 still has to clear the Rules Committee this week, and in both cases it would be helpful for people to reach out to our local legislators and tell them to oppose these bills.” The bad news from Tallahassee doesn’t stop there. Florida Forever, the state’s conservation and recreation land acquisition program which is funded by doc stamps, started in 2001 at $300 million/year. Funding was cut to zero during the Great Recession but rebounded to $100 million in 2018-2023 and then came all the way back up to $270 million last year. Alas; this year the Governor requested only $115 million. Even worse, the Senate wants to appropriate just $35 million for Florida Forever. The House’s number: A Big Fat Zero. Meanwhile, Lake Okeechobee hasn’t seen any serious effects from the drought thus far. It’s currently at 12.26 feet, and it would have to drop below 11 feet for 80 days before triggering any real concerns. The main problem with the lake right now Is actually to the west: The Caloosahatchee River needs fresh water, but the low lake level is preventing it from getting enough. At least the drought is giving the St. Lucie Estuary a breather from discharge threats. -- Walter Deemer, LWVMC Rivers Coalition Representative

The featured presenter at the January 22nd Rivers Coalition meeting was Army Corps of Engineers Jacksonville District Commander Col. Brandon Bowman. He reported: * The Lake Okeechobee management effort is going well. The lake level is currently a near-ideal 13.01 feet. In addition, following last summer’s Lake Recovery Operation, Submerged Aquatic Vegetation (“sea grass”) now covers 20,000 acres of the lake bottom compared with just 3000 acres beforehand. * All stakeholders but one are having their needs met at the present time: The Caloosahatchee River west of the lake isn’t receiving nearly as much fresh water as it needs. * The biggest threat to the St. Lucie Estuary right now isn’t discharges from Lake Okeechobee; it’s polluted runoff flowing into the headwaters of the North Fork. The Corps has several projects underway to address that issue. * The Everglades restoration effort continues moving forward, albeit at a seemingly-glacial pace. To wit: Col. Bowman was happy to announce that the Everglades Agricultural Area projects would be completed five years ahead of schedule – but that still won’t be until the end of 2029. * The big C-44 Reservoir, just north of the St. Lucie Canal in western Martin County, is a key part of the management plan. The reservoir will store runoff and remove phosphorus before discharging the water. Unfortunately, it hasn’t been able to operate at capacity; there’s a seepage issue at one end, and it can only be filled to ten feet compared with its designed fifteen-foot level. The Corps doesn’t think the reservoir will be able to be filled to capacity until 2032. * Finally, Coalition members expressed a great deal of alarm about the Corps’ Engineering Research and Development Center’s plan to develop treatments to remove peroxide and phosphorus from the water. The concern stems from the ERDC’s need to test those treatments, and they have to do the testing in the St. Lucie Canal. There was widespread fear that this could produce harmful results in our canal and our estuary. On the legislative front, Gil Smart, the Friends of the Everglades monitor of the goings-on in Tallahassee, shook his head: “If last year’s legislative session’s theme was facilitating sprawl, this year’s is sprawl on steroids.” A disturbingly large number of bills have been filed that will allow more and more development projects to be subject only to administrative approval rather than, as now, being required to go through a public review process. If these bills pass they will drastically reduce public input on some very big and impactful development proposals -- and completely eliminate it in some cases. As these and other really bad bills get rammed towards the finish line, you will undoubtably be receiving calls for action from your favorite environmental organization. Keep an eye on your inbox. -- Walter Deemer, LWVMC Rivers Coalition Representative
