A 30-year rescue moved the plant from six individuals to 28 adults at two sites on Isabela. Its first natural recruitment, four seedlings found in 2021, did not survive the dry spell that followed.

Set the two counts side by side. Ninety-four nursery-grown shrubs went into the volcanic ground of Isabela between 2017 and 2024 under the Galapagos Verde 2050 program [3], and six wild plants were clinging to cracks in the flows of Darwin Volcano when the species bottomed out in 2007 [11]. That is a hundred individuals either placed or already present. The census today is 28 healthy adults [2], which is 28 percent of that total [1]. The material does not say how many of the 94 are among the 28, or how many are still below adult size, so that percentage brackets the attrition rather than measures it. What it does establish is that the planting effort has been running at roughly a dozen shrubs a year [3] to yield a net gain of 22 adults over 18 years [2].
The nursery half of the problem now has engineering behind it. The team reports 100 percent survival among the transplants tested with the Groasis Waterboxx, a water-retention device [7], and worked out that young plants build roots before they put on visible top growth, which told them when a plant was ready to leave the nursery [13]. Both fixes share a precondition: someone chooses the spot and installs the hardware.
The four seedlings found in lava cracks at Playa Tortuga Negra in 2021 chose their own spots [4]. None of them survived the drought that followed [5]. Wild-germinated survivorship in this population therefore stands at zero out of four [4], and the source does not report that any water aid was extended to them.
That is the substitution worth noticing. The original collapse is attributed to historical grazing by introduced herbivores [11], a pressure that fencing and eradication can act on. The failure documented in 2021 is water, which the authors name as one of the biggest ongoing threats to the plant [6]. A restoration program can propagate its way out of a grazing problem. It cannot propagate its way out of a dry season, because the generation that has to survive the dry season is the one it did not plant.
The 2024 return to Caleta Tagus, where the 1962 herbarium specimen that started all of this was collected [9], is 62 years of institutional patience [5], and it currently amounts to eight plants at that site [10]. Eight plants is a number a single bad year reaches, and the record already shows a bad year reaching a cohort. Patricia Jaramillo Diaz, the lead author, sets the bar herself: true restoration begins when nature no longer depends on us [12]. Her own recruitment data say it has not begun yet.
Ranked by verification strength, evidence, and original report placement.
A 30-year conservation effort has helped the critically endangered Galapagos snapdragon (Galvezia leucantha subsp. leucantha) recover from just six individuals to a small, carefully tended wild population.
The wild adult population has grown from six individuals in 2007 to 28 healthy adults today: 20 at Playa Tortuga Negra and 8 at Tagus Cove.
The Galapagos Verde 2050 program outplanted 94 nursery-grown shrubs into the volcanic landscapes of Isabela between 2017 and 2024.
In 2021, researchers monitoring the reintroduced population at Playa Tortuga Negra found four naturally recruited seedlings growing in cracks in the lava rock, the first evidence of natural seedling regeneration in the wild.
Those first naturally recruited seedlings did not survive the drought that followed.
Water scarcity remains one of the biggest ongoing threats to the critically endangered plant.

Evidence-backed comparisons of source perspectives and observed adoption signals. Read the methodology
Which Builder, Operator, and Investor concerns the observed source mix emphasized—not a truth score.
Evidence, demonstrated adoption, hype gap, incentives, and confidence are assessed independently, each on its own current evidence. How these are measured.
Specific counts from a published study, but only one institutional retelling
The core figures are unusually concrete for a press write-up: 6 individuals in 2007, 94 outplants 2017-2024, 28 adults split 20/8, four seedlings in 2021 and their loss. They come from a peer-reviewed paper in Nature Conservation with a named lead author. Against that, the entire cluster is a single publisher relaying the study team's own account, key quantitative results (the 100% Waterboxx survival) arrive without denominators, and no cohort survival accounting is offered for the 94 outplants, so several load-bearing numbers cannot be independently bounded.
Real field deployment, but one species at two sites by one program
There is genuine deployed practice rather than a proposal: 94 shrubs outplanted over eight years, two active restoration sites, a 2024 range-restoration action, and standing monitoring that detected and then followed the loss of wild recruits. Adoption stops there — the work sits inside a single program (Galapagos Verde 2050) with the Charles Darwin Foundation and Galapagos National Park Directorate, involves 28 standing adults, and the supplied material shows no other program or geography taking up the methods it calls a scalable blueprint.
Recovery and 'scalable blueprint' framing runs ahead of 28 adults and zero surviving wild recruits
The framing — 'now recovering', a 'scalable blueprint' for island endemics, plants that 'thrive' — is stronger than the underlying numbers support: a population of 28 human-planted adults at two sites, no surviving naturally germinated offspring, water scarcity still named as the main threat, and no replication elsewhere. The overstatement is moderate rather than severe because the source itself reports the drought loss, keeps the self-sustaining test in view via the lead author's own quote, and does not hide that the next step is merely sustained action.
Study team and host institution are the sole voices, with reputational and continuation stakes
Every substantive claim, quote and number originates with the study's lead author and the Charles Darwin Research Station / Galapagos Verde 2050 program, relayed by a single aggregating publisher in release-style form, and the text closes by arguing for continued propagation, monitoring and long-term management — i.e. continuation of the program described. A named commercial product (Groasis Waterboxx) is credited with a 100% result without disclosed methodology. No outside reviewer, competing program, or funder appears anywhere in the supplied material.
Internally consistent single-publisher record with no corroboration
Confidence is capped by structure: one publisher, one underlying institutional account, and no independent replication of any figure. It is not lower because the numbers are specific, internally consistent between the lede and the status section, tied to a named peer-reviewed paper and author, and because the source reports its own negative result — patterns that usually indicate a faithful relay of the study rather than embellishment.
