Hi!, I'm pretty sure that the name is wrongly spelled, the place is called: "Vivero Dunícola Florentino Ameghino", there's a c-letter lacking in the second word.
Here's an article just as an example of the writing: https://regionmardelplata.com/ver-noticia.asp?noticia=general-alvarado-el-vivero-de-miramar-es-objeto-de-controversias&codigo=9709

Best regards and thanks a lot for your work!
