Herbaria preserve plants outside the environments and moments in which they once lived. Collected, dried, and mounted on paper, the specimens retain their visible structures while losing their color, movement, and ecological surroundings. An herbarium sheet is therefore both a scientific record and the material trace of an encounter: a particular plant, found by a particular person, in a particular place and time.

​

Some specimens survive long after the landscapes from which they were collected have been transformed. They may become the remaining evidence that a species once inhabited a region from which it has since disappeared. The plant persists on paper, while the soil, water, pollinators, neighboring organisms, and human communities that sustained it remain outside the archive.

​

Herbaria begins with this separation between the preserved specimen and its absent world. Using historical herbarium materials as sources, Debora Hirsch reconstructs selected plants through digital painting and animation. For a brief interval, the static specimen appears to recover movement, volume, and time. It emerges, grows, and changes before vanishing once again. This return is intentionally incomplete. 

​​

In the animation, an existence is compressed into a few moments. Emergence, growth, transformation, and disappearance follow one another with unnatural speed. The plant appears long enough to establish its presence before receding again. Its second disappearance alludes to the difficulty, and sometimes the impossibility, of restoring an ecosystem after its relationships have been broken.

​​

A species is more than a population of individual organisms. It is also an accumulation of dependencies. Its survival may rely on a particular pollinator, fungus, animal, water cycle, soil composition, or climatic rhythm. When one species disappears, the loss travels outward through these relationships. Pollination patterns change, food sources diminish, and habitats become less stable. Other organisms may decline in turn. What vanishes is not simply one form of life, but part of the structure through which many forms of life become possible.

​​

The plants in these works therefore appear alone. Their solitude reflects the logic of the herbarium sheet, where the specimen is preserved as an individual, and it points toward the isolation produced by ecological fragmentation. Each plant occupies an imagined environment that bears the trace of a world but cannot recreate its full complexity. The animation offers neither resurrection nor restoration. It creates a temporary encounter with what an archive can retain and with everything it must leave behind.

​​

Within this brief interval, the plants seem suspended between historical evidence and speculative life. Their forms originate in specimens collected for scientific study, yet animation releases them from the stillness imposed by the page. Leaves unfold from compressed surfaces, stems regain volume, and flowers open according to a temporal order invented within the work. The resulting plants belong neither entirely to the archive nor to the natural world. They occupy a third condition, produced through memory, technology, and imagination.

​​

This condition reveals a further ambiguity. Preservation protects something from disappearance, but it also changes the thing being preserved. The living plant becomes a dried specimen; the specimen becomes an image; the image becomes data; and the data becomes movement. At every stage, something is retained and something is lost. Herbaria follows these transformations without claiming that the final image can recover an original or complete form of life.

​​

Two species represented in the work reveal different dimensions of this condition:

​​

The American chestnut, Castanea dentata, once formed a dominant presence in the forests of eastern North America. It provided food and shelter for wildlife, while its timber and nuts supported human communities and rural economies. During the twentieth century, chestnut blight transformed the species from a vast component of the forest canopy into a scattered population of surviving roots, shoots, and isolated mature trees. The tree did not disappear completely, but the ecological world structured around its former abundance was profoundly altered.

Current restoration efforts involve breeding, hybridization, conservation, and genetic research. These initiatives carry the possibility that the American chestnut may one day return to parts of its historical range. Yet bringing back the tree as a viable organism is different from restoring the forest that once formed around it. The question is not only whether the species can be recovered, but whether the relationships accumulated through centuries of coexistence can also be reconstructed.

The chestnut therefore occupies an uncertain position between absence and survival. It remains present through living remnants, preserved specimens, historical photographs, written accounts, and scientific research. The effort to restore the species must confront not only a biological problem, but also the temporal distance separating the surviving tree from its former ecological world.

​

Helonias bullata, commonly known as swamp pink, belongs to the wetlands of the eastern United States. It grows in saturated forest soils, along streams, and in swampy habitats whose hydrological balance is easily disturbed. The plant depends upon the persistence of water, shade, pollinating insects, and surrounding vegetation. Drainage, development, water diversion, pollution, and habitat fragmentation threaten not only the plant itself but the precise conditions under which it can reproduce.

Historically recorded in Staten Island and other parts of New York, Helonias bullata has disappeared from much of its former regional range. In fragmented habitats, pollinators may visit less frequently, increasing the plant’s dependence on self-pollination and reducing the genetic exchange that supports resilient populations. Restoration therefore cannot consist solely of returning individual plants to the landscape. It requires the recovery of wetland hydrology, habitat continuity, pollinator activity, and the network of species with which the plant evolved.

The vulnerability of Helonias bullata is difficult to separate from the vulnerability of its habitat. Its disappearance cannot be understood as the isolated failure of one species. It belongs to a larger history of drained wetlands, altered waterways, fragmented forests, and diminished pollinator communities. 

​​

In the artwork, these plants reappear without the worlds that once surrounded them. They are visually present but ecologically displaced. Their movement gives them a temporary vitality, while their solitude reveals the insufficiency of representation. The image can recall the form of a plant, but it cannot reproduce the totality of it.

The herbarium preserves through stillness. Animation introduces duration into the preserved form. Between these two procedures, one that arrests movement and another that simulates its return, the plant occupies an unstable interval. 

In this interval, preservation becomes a question rather than an assurance. What does it mean to preserve the image of a species while the conditions of its existence disappear? What kind of knowledge survives in a specimen, and what remains inaccessible when a living network is reduced to a single body on a sheet of paper?

Herbaria does not attempt to restore a lost world. It makes visible the distance between the specimen and the ecosystem, between the persistence of an image and the vulnerability of a living species. The archive remembers one plant at a time. The ecosystem exists through relationships. The work inhabits the space between them.
